  • What Is Different? Between Impulse Noise and Electrical Fast Transient Burst】
    【What is different? Between Impulse Noise and Electrical Fast Transient Burst】 The Inquiry about "a distinction between an impulse noise simulator (following and our company model INS series) and a Fast transient Burst simulator (following and our company model FNS series)" is one of the major questions in a lot of quries from customers. Herewith the difference is focused and presented. The phenomenon which are reproduced and backgraound Both INS and FNS reproduce phenomenon of back electromotive energy noise which may be generated in ON/OFF of power supply switching (like a gas insulated braker and/or electromagnetism relay, etc.). INS was introduced by Mr. Manohar L.Tandor (at that time worked in I.B.M) as a simulator of the high frequency noise to data processing apparatus in the 1960s, and the computer maker of those days adopted it in the 1970s, and it spread widely. FNS is indicated as a basic standard of the immunity type test which reproduces the malfunction by the noise phenomenon of switching ON/OFF and adopted not only in Europe but also world-wide. The 1st edition of Standard for this test was issued as IEC801-4 in IEC TC65 (Industrial Process Controls) in 1988. Then, in order to adopt to all the electric devices, IEC1000-4-4 was issued in 1995. Moreover, in order to differenciate the numbering between ISO and IEC, “60000” has been added to the Stadanrd number. Consequently, it has been named as IEC61000-4-4. output waveform Rise time / the pulse width [INS] It is a rectangular wave whose pulse width is 50ns-1μs and rise time is less than 1ns.

  • Convolutional Codes in Vss
    CONVOLUTIONAL CODES IN VSS . .. By: Dr. Kurt R. Matis Director of Systems Research SIMULATION OF CONVOLUTIONAL CODES IN VSS This document describes the modeling and simulation of short constraint- length convolutional codes used in conjunction with Viterbi decoding in the Visual System Simulator (VSS). After a brief review of the history and application of convolutional codes, a detailed description of VSS models for encoding/decoding of these codes is presented. Step-by-step examples illustrate how to construct simulations and analyze results. Convolutional Code Basics This note begins with some background information on the use of convolutional codes. The development of convolutional codes is discussed along with a history of important applications. This information is meant to provide a perspective on the selection of the convolutional code models that are provided in VSS. Transmission efficiency and reliability can be improved by encoding information digits in a way that creates an interdependence between symbols which are transmitted over a channel. At the receiving end, the interdependence can be exploited to detect or even correct transmission errors, provided erroneous symbols are not received too frequently. Such coding is called error-control coding and is shown in the configuration of Figure 1.

  • AN-1496 Noise, TDMA Noise, and Suppression Techniques (Rev. D)
    Application Report SNAA033D–May 2006–Revised May 2013 AN-1496 Noise, TDMA Noise, and Suppression Techniques ..................................................................................................................................................... ABSTRACT The term “noise” is often and loosely used to describe unwanted electrical signals that distort the purity of the desired signal. Some forms of noise are unavoidable (e.g., real fluctuations in the quantity being measured), and they can be overcome only with the techniques of signal averaging and bandwidth narrowing. Other forms of noise (for example, radio frequency interference and “ground loops”) can be reduced or eliminated by a variety of techniques, including filtering and careful attention to wiring configuration and parts location. Finally, there is noise that arises in signal amplification and it can be reduced through the techniques of low-noise amplifier design. Although noise reduction techniques can be effective, it is prudent to begin with a system that is free of preventable interference and that possesses the lowest amplifier noise possible1. This application note will specifically address the problem of TDMA Noise customers have encountered while driving mono speakers in their GSM phone designs.

    IEEE TRANSACTIONS ON COMMUNICATIONS, VOL. 56, NO. 11, NOVEMBER 2008 1807 CRC-Assisted Error Correction in a Convolutionally Coded System Renqiu Wang, Member, IEEE, Wanlun Zhao, Member, IEEE, and Georgios B. Giannakis, Fellow, IEEE Abstract—In communication systems employing a serially When the signal to noise ratio (SNR) is relatively high, only a concatenated cyclic redundancy check (CRC) code along with small number of errors are typically present in an erroneously a convolutional code (CC), erroneous packets after CC decoding decoded packet. Instead of discarding the entire packet, the are usually discarded. The list Viterbi algorithm (LVA) and the iterative Viterbi algorithm (IVA) are two existing approaches theme is this paper is to possibly recover it by utilizing jointly capable of recovering erroneously decoded packets. We here ECC and CRC. employ a soft decoding algorithm for CC decoding, and introduce We will study a system with serially concatenated CRC and several schemes to identify error patterns using the posterior CC (CRC-CC). Being a special case of conventional serially information from the CC soft decoding module. The resultant iterative decoding-detecting (IDD) algorithm improves error concatenated codes (CSCC) [1], CRC-CC has been widely performance by iteratively updating the extrinsic information applied in wireless communications, for example, in an IS-95 based on the CRC parity check matrix. Assuming errors only system. Various approaches are available to recover erroneous happen in unreliable bits characterized by small absolute values packets following the Viterbi decoding stage. One of them is of the log-likelihood ratio (LLR), we also develop a partial IDD based on the list Viterbi algorithm (LVA), which produces a (P-IDD) alternative which exhibits comparable performance to IDD by updating only a subset of unreliable bits.

  • Understanding Noise Figure
    Understanding Noise Figure Iulian Rosu, YO3DAC / VA3IUL, http://www.qsl.net/va3iul One of the most frequently discussed forms of noise is known as Thermal Noise. Thermal noise is a random fluctuation in voltage caused by the random motion of charge carriers in any conducting medium at a temperature above absolute zero (K=273 + °Celsius). This cannot exist at absolute zero because charge carriers cannot move at absolute zero. As the name implies, the amount of the thermal noise is to imagine a simple resistor at a temperature above absolute zero. If we use a very sensitive oscilloscope probe across the resistor, we can see a very small AC noise being generated by the resistor. • The RMS voltage is proportional to the temperature of the resistor and how resistive it is. Larger resistances and higher temperatures generate more noise. The formula to find the RMS thermal noise voltage Vn of a resistor in a specified bandwidth is given by Nyquist equation: Vn = 4kTRB where: k = Boltzmann constant (1.38 x 10-23 Joules/Kelvin) T = Temperature in Kelvin (K= 273+°Celsius) (Kelvin is not referred to or typeset as a degree) R = Resistance in Ohms B = Bandwidth in Hz in which the noise is observed (RMS voltage measured across the resistor is also function of the bandwidth in which the measurement is made). As an example, a 100 kΩ resistor in 1MHz bandwidth will add noise to the circuit as follows: -23 3 6 ½ Vn = (4*1.38*10 *300*100*10 *1*10 ) = 40.7 μV RMS • Low impedances are desirable in low noise circuits.
