  • Lecture 11 : Discrete Cosine Transform Moving Into the Frequency Domain
    Lecture 11 : Discrete Cosine Transform Moving into the Frequency Domain Frequency domains can be obtained through the transformation from one (time or spatial) domain to the other (frequency) via Fourier Transform (FT) (see Lecture 3) — MPEG Audio. Discrete Cosine Transform (DCT) (new ) — Heart of JPEG and MPEG Video, MPEG Audio. Note : We mention some image (and video) examples in this section with DCT (in particular) but also the FT is commonly applied to filter multimedia data. External Link: MIT OCW 8.03 Lecture 11 Fourier Analysis Video Recap: Fourier Transform The tool which converts a spatial (real space) description of audio/image data into one in terms of its frequency components is called the Fourier transform. The new version is usually referred to as the Fourier space description of the data. We then essentially process the data: E.g . for filtering basically this means attenuating or setting certain frequencies to zero We then need to convert data back to real audio/imagery to use in our applications. The corresponding inverse transformation which turns a Fourier space description back into a real space one is called the inverse Fourier transform. What do Frequencies Mean in an Image? Large values at high frequency components mean the data is changing rapidly on a short distance scale. E.g .: a page of small font text, brick wall, vegetation. Large low frequency components then the large scale features of the picture are more important. E.g . a single fairly simple object which occupies most of the image. The Road to Compression How do we achieve compression? Low pass filter — ignore high frequency noise components Only store lower frequency components High pass filter — spot gradual changes If changes are too low/slow — eye does not respond so ignore? Low Pass Image Compression Example MATLAB demo, dctdemo.m, (uses DCT) to Load an image Low pass filter in frequency (DCT) space Tune compression via a single slider value n to select coefficients Inverse DCT, subtract input and filtered image to see compression artefacts.

  • Acquiring an Analog Signal: Bandwidth, Nyquist Sampling Theorem, and Aliasing
    Acquiring an Analog Signal: Bandwidth, Nyquist Sampling Theorem, and Aliasing Overview Learn about acquiring an analog signal, including topics such as bandwidth, amplitude error, rise time, sample rate, the Nyquist Sampling Theorem, aliasing, and resolution. This tutorial is part of the Instrument Fundamentals series. Contents wwWhat is a Digitizer? wwBandwidth a. Calculating Amplitude Error b. Calculating Rise Time wwSample Rate a. Nyquist Sampling Theorem b. Aliasing wwResolution wwSummary ni.com/instrument-fundamentals Next Acquiring an Analog Signal: Bandwidth, Nyquist Sampling Theorem, and Aliasing What Is a Digitizer? Scientists and engineers often use a digitizer to capture analog data in the real world and convert it into digital signals for analysis. A digitizer is any device used to convert analog signals into digital signals. One of the most common digitizers is a cell phone, which converts a voice, an analog signal, into a digital signal to send to another phone. However, in test and measurement applications, a digitizer most often refers to an oscilloscope or a digital multimeter (DMM). This article focuses on oscilloscopes, but most topics are also applicable to other digitizers. Regardless of the type, the digitizer is vital for the system to accurately reconstruct a waveform. To ensure you select the correct oscilloscope for your application, consider the bandwidth, sampling rate, and resolution of the oscilloscope. Bandwidth The front end of an oscilloscope consists of two components: an analog input path and an analog-to-digital converter (ADC). The analog input path attenuates, amplifies, filters, and/or couples the signal to optimize it in preparation for digitization by the ADC.

  • Signal Shorts
    Signal Shorts Bill Fawcett Director of Engineering The Problem WMRA has published a coverage map which shows where we expect our signal to reach, based on formulas devised by the FCC. Yet even within our established coverage area, there are locales in which the signal sounds "fuzzy". In most cases, the topography of the area is causing "multi-path" interference, that is, reflections of the signal off of nearby mountains adds to the direct signal, but delayed somewhat in time, and scrambles the received signal. This is the same phenomenon that causes "ghosts" on your TV (shadow- images on your screen, not the "X-Files"). Multipath is a significant problem along the I-81 corridor North of Harrisonburg to Strasburg. Also at Penn Laird along Route 33. Multipath problems are so site-specific that moving a radio a few feet may make a difference. The next time you get a fuzzy signal at a traffic light you may note that it clears up by advancing a few feet (watch out for the car in front of you, or you may have other, more serious, problems). Switching to mono, if possible, will also help. Other areas suffer from terrain obstructions. This may be noted at Massanutten Resort, and in the UVA area of Charlottesville. For those outside of the predicted coverage area, signal strength (the lack of) may be a problem, as may interference. North of Charlottesville this is a big problem, with interference from a high-power station in Washington D.C. causing problems. Lastly, the downtown Charlottesville area suffers from interference from WCYK's 105.1 translator.

  • Digital Television: Has the Revolution Stalled?
    iBRIEF / Media & Communications Cite as 2001 Duke L. & Tech. Rev. 0014 3/26/2001 April 26, 2001 DIGITAL TELEVISION: HAS THE REVOLUTION STALLED? When digital television technology first hit the scene it garnered great excitement, with its promise of movie theater picture and sound on a fraction of the bandwidth of analog. A plan was implemented to transition from the current analog broadcasting system to a digital system effective December 23, 2006. As we reach the half point of this plan, the furor begins to die as the realities of the difficult change sink in. The History of Digital Television ¶1 The technological possibilities of digital television are immense.1 It could provide the broadcast of theater quality sound and picture via cable, antenna or satellite; multicasting which enables the transmission of multiple programs within one digital signal; and signals for data communications that could potentially bring to the TV the capabilities of web pages and interactive compact discs.2 ¶2 The motivation behind the development of digital television technologies can be traced back to the history of analog broadcasting. As television became a viable medium in the United States at the start of the Second World War, the establishment of technical standards in transmission and reception equipment was of vital importance. In 1940, the National Television Systems Committee (NTSC) met to determine guidelines for the transmission and reception of television signals. With the US leading the charge into early broadcasting in the late 1940s, the technology available at the time became entrenched and remains a part of our lives today, with the familiar 525-line low-resolution screens that bring us the evening news.
