Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: A good quality soldering iron (25-40W) with a small tip. Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections. When solder rolls off the tip, it needs cleaning. Thin raisin-core solder. Do not use any flux or grease. A diagonal cutter to trim excess wires.

Kuijper (TNO Defence, Security and Safety) University of Twente Cluster: Human Media Interaction (HMI) Department of Electrical Engineering, Mathematics and Computer Science (EEMCS) Abstract Currently, during the creation of a simulator that uses Virtual Reality, 3D content creation is by far the most time consuming step, of which a large part is done by hand. This is no different for the creation of virtual urban environments. In order to speed up this process, city generation systems are used. At re-lion, an overall design was specified in order to implement such a system, of which the first step is to automatically create realistic city boundaries. Within the scope of a research project for the University of Twente, an algorithm is proposed for this first step. This algorithm makes use of two-dimensional Perlin noise to fill a grid with random values. After applying a transformation function, to ensure a minimum amount of clustering, and a threshold mech- anism to the grid, the hull of the resulting shape is converted to a vector representation.

  • City of San Diego Noise Element
    Noise Element Noise Element Noise Element Purpose To protect people living and working in the City of San Diego from excessive noise. Introduction Noise at excessive levels can affect our environment and our quality of life. Noise is subjective since it is dependent on the listener’s reaction, the time of day, distance between source and receptor, and its tonal characteristics. At excessive levels, people typically perceive noise as being intrusive, annoying, and undesirable. The most prevalent noise sources in San Diego are from motor vehicle traffic on interstate freeways, state highways, and local major roads generally due to higher traffic volumes and speeds. Aircraft noise is also present in many areas of the City. Rail traffic and industrial and commercial activities contribute to the noise environment. The City is primarily a developed and urbanized city, and an elevated ambient noise level is a normal part of the urban environment. However, controlling noise at its source to acceptable levels can make a substantial improvement in the quality of life for people living and working in the City. When this is not feasible, the City applies additional measures to limit the effect of noise on future land uses, which include spatial separation, site planning, and building design techniques that address noise exposure and the insulation of buildings to reduce interior noise levels. The Noise Element provides goals and policies to guide compatible land uses and the incorporation of noise attenuation measures for new uses to protect people living and working in the City from an excessive noise environment. This purpose becomes more relevant as the City continues to grow with infill and mixed-use development consistent with the Land Use Element.

  • MT-004: the Good, the Bad, and the Ugly Aspects of ADC Input Noise-Is
    MT-004 TUTORIAL The Good, the Bad, and the Ugly Aspects of ADC Input Noise—Is No Noise Good Noise? by Walt Kester INTRODUCTION All analog-to-digital converters (ADCs) have a certain amount of "input-referred noise"— modeled as a noise source connected in series with the input of a noise-free ADC. Input-referred noise is not to be confused with quantization noise which only occurs when an ADC is processing an ac signal. In most cases, less input noise is better, however there are some instances where input noise can actually be helpful in achieving higher resolution. This probably doesn't make sense right now, so you will just have to read further into this tutorial to find out how SOME noise can be GOOD noise. INPUT-REFERRED NOISE (CODE TRANSITION NOISE) Practical ADCs deviate from ideal ADCs in many ways. Input-referred noise is certainly a departure from the ideal, and its effect on the overall ADC transfer function is shown in Figure 1. As the analog input voltage is increased, the "ideal" ADC (shown in Figure 1A) maintains a constant output code until the transition region is reached, at which point the output code instantly jumps to the next value and remains there until the next transition region is reached. A theoretically perfect ADC has zero "code transition" noise, and a transition region width equal to zero. A practical ADC has certain amount of code transition noise, and therefore a transition region width that depends on the amount of input-referred noise present (shown in Figure 1B).

Markham St., Little Rock, AR 72205, USA * Correspondence: [email protected] Abstract: White noise generators can use uniform random sequences as a basis. However, such a technology may lead to deficient results if the original sequences have insufficient uniformity or omissions of random variables. This article offers a new approach for creating a phase signal generator with an improved matrix of autocorrelation coefficients. As a result, the generated signals of the white noise process have absolutely uniform intensities at the eigen Fourier frequencies. The simulation results confirm that the received signals have an adequate approximation of uniform white noise.

  • Reducing ADC Quantization Noise
    print | close Reducing ADC Quantization Noise Microwaves and RF Richard Lyons Randy Yates Fri, 2005­06­17 (All day) Two techniques, oversampling and dithering, have gained wide acceptance in improving the noise performance of commercial analog­to­digital converters. Analog­to­digital converters (ADCs) provide the vital transformation of analog signals into digital code in many systems. They perform amplitude quantization of an analog input signal into binary output words of finite length, normally in the range of 6 to 18 b, an inherently nonlinear process. This nonlinearity manifests itself as wideband noise in the ADC's binary output, called quantization noise, limiting an ADC's dynamic range. This article describes the two most popular methods for improving the quantization noise performance in practical ADC applications: oversampling and dithering. Related Finding Ways To Reduce Filter Size Matching An ADC To A Transformer Tunable Oscillators Aim At Reduced Phase Noise Large­Signal Approach Yields Low­Noise VHF/UHF Oscillators To understand quantization noise reduction methods, first recall that the signal­to­quantization­noise ratio, in dB, of an ideal N­bit ADC is SNRQ = 6.02N + 4.77 + 20log10 (LF) dB, where: LF = the loading factor measure of the ADC's input analog voltage level. (A derivation of SNRQ is provided in ref. 1.) Parameter LF is defined as the analog input root­mean­square (RMS) voltage divided by the ADC's peak input voltage. When an ADC's analog input is a sinusoid driven to the converter's full­scale voltage, LF = 0.707. In that case, the last term in the SNRQ equation becomes −3 dB and the ADC's maximum output­ signal­to­noise ratio is SNRQ­max = 6.02N + 4.77 −3 = 6.02N + 1.77 dB.

  • Procedural Generation of Infinite Terrain from Real-World Elevation
    Journal of Computer Graphics Techniques Vol. 3, No. 1, 2014 http://jcgt.org Designer Worlds: Procedural Generation of Infinite Terrain from Real-World Elevation Data Ian Parberry University of North Texas Figure 1.A 180◦ panorama of terrain generated using elevation data from Utah. Abstract The standard way to procedurally generate random terrain for video games and other applica- tions is to post-process the output of a fast noise generator such as Perlin noise. Tuning the post-processing to achieve particular types of terrain requires game designers to be reason- ably well-trained in mathematics. A well-known variant of Perlin noise called value noise is used in a process accessible to designers trained in geography to generate geotypical terrain based on elevation statistics drawn from widely available sources such as the United States Geographical Service. A step-by-step process for downloading and creating terrain from real- world USGS elevation data is described, and an implementation in C++ is given. 1. Introduction Terrain generation is an example of what is known in the game industry as procedu- ral content generation. Procedural content generation needs to have three important properties. First, it needs to be fast, meaning that it has to use only a fraction of the computing power on a current-generation computer. Second, it needs to be both ran- dom and structured so that it creates content that is varied and interesting. Third, it needs to be controllable in a natural and intuitive way. As noted in the excellent survey paper by Smelik et al. [2009], procedural terrain generation is often based on fractal noise generators such as Perlin noise [Perlin 1985; Perlin 2002] (for more details see, for example, the book by Ebert et al.
