Spectra and Bandwidth of Emissions (Question ITU-R 222/1)
Rec. ITU-R SM.328-11 1 RECOMMENDATION ITU-R SM.328-11* Spectra and bandwidth of emissions (Question ITU-R 222/1) (1948-1951-1953-1956-1959-1963-1966-1970-1974-1978-1982-1986-1990-1994-1997-1999-2006) Scope This Recommendation gives definitions, analytical models and other considerations of the values of emission components for various emission types as well as the usage of these values from the standpoint of spectrum efficiency. Keywords Spurious emission, dB bandwidth, emitted spectra, adjacent-channel, necessary band The ITU Radiocommunication Assembly, considering a) that in the interest of an efficient use of the radio spectrum, it is essential to establish for each class of emission rules governing the spectrum emitted by a transmitting station; b) that, for the determination of an emitted spectrum of optimum width, the whole transmission circuit as well as all its technical working conditions, including other circuits and radio services sharing the band, the transmitter frequency tolerances of Recommendation ITU-R SM.1045, and particularly propagation phenomena, should be taken into account; c) that the concepts of “necessary bandwidth” and “occupied bandwidth” defined in Nos. 1.152 and 1.153 of the Radio Regulations (RR), are the basis for specifying the spectral properties of a given emission, or class of emission, in the simplest possible manner; d) that, however, these definitions do not suffice when consideration of the complete problem of radio spectrum efficiency is involved; and that an endeavour should be made to establish -

NTE1416 Integrated Circuit Chrominance and Luminance Processor for NTSC Color TV
NTE1416 Integrated Circuit Chrominance and Luminance Processor for NTSC Color TV Description: The NTE1416 is an MSI integrated circuit in a 28–Lead DIP type package designed for NTSC systems to process both color and luminance signals for color televisions. This device provides two functions: The processing of color signals for the band pass amplifier, color synchronizer, and demodulator cir- cuits and also the processing of luminance signal for the luminance amplifier and pedestal clamp cir- cuits. The number of peripheral parts and controls can be minimized and the manhours required for assembly can be considerbly reduced. Features: D Few External Components Required D DC Controlled Circuits make a Remote Controlled System Easy D Protection Diodes in every Input and Output Pin D “Color Killer” Needs No Adjustements D “Contrast” Control Does Not Prevent the Natural Color of the Picture, as the Color Saturation Level Changes Simultaneously D ACC (Automatic Color Controller) Circuit Operates Very Smoothly with the Peak Level Detector D “Brightness Control” Pin can also be used for ABL (Automatic Beam Limitter) Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Supply Voltage, VCC . 14.4V Brightness Controlling Voltage, V3 . 14.4V Resolution Controlling Voltage, V4 . 14.4V Contrast Controlling Voltage, V10 . 14.4V Tint Controlling Voltage, V7 . 14.4V Color Controlling Voltage, V9 . 14.4V Auto Controlling Voltage, V8 . 14.4V Luminance Input Signal Voltage, V5 . +5V Chrominance Signal Input Voltage, V13 . +2.5V Demodulator Input Signal Voltage, V25 . +5V R.G.B.

Tektronix Television Systems Measurement Concepts 062-1064-00
Measurement Concepts Television Systems TELEVISION SYSTEM MEASUREMENTS BY GERALD A. EASTMAN MEASUREMENT CONCEPTS INTRODUCTION The primary intent of this book is to acquaint the reader with the functional elements of a television broadcast studio and some of the more common diagnostic and measurement concepts on which video measurement techniques are based. In grouping the functional elements of the broadcasting studio, two areas of primary concern can be identified -- video signal sources and the signal routing path from the source to the transmitter. The design and maintenance of these functional elements is based in large measure on their use and purpose. Understanding the use and purpose of any device always enhances the engineer's or technician's ability to maintain the performance initially designed into the equipment. The functional elements of the broadcast studio will be described in the first portion of this book including a brief discussion of how these functional elements interrelate to form an integrated system. In the broadcasting studio, once the video sources and routing systems are initially established, maintaining quality control of both the sources and the routing path becomes one of the major concerns of the broadcast engineer. Since the picture information is transmitted as a video waveform, quality control can in large measure be accomplished in terms of waveform distortions and subjective picture quality degradations. Four major test waveforms, each designed to observe and measure a specific type of distortion, are commonly used in a broadcast studio. The diagnostic information contained in each waveform will be described in the latter portion of this book in terms of the measurements commonly made with each of the four waveforms. -

Simulation and Measurement of the Transmission Distortions of the Digital Television DVB-T/H Part 1: Modulator for Digital Terrestrial Television
338 R. ŠTUKAVEC, T. KRATOCHVÍL, SIMULATION AND MEASUREMENT … PART 1: MODULATOR FOR DTT Simulation and Measurement of the Transmission Distortions of the Digital Television DVB-T/H Part 1: Modulator for Digital Terrestrial Television Radim ŠTUKAVEC, Tomáš KRATOCHVÍL Dept. of Radio Electronics, Brno University of Technology, Purkyňova 118, 612 00 Brno, Czech Republic [email protected], [email protected] Abstract. The paper deals with the first part of results of the Czech Science Foundation research project that was aimed into the simulation and measurement of the transmission distortions of the digital terrestrial television according to DVB-T/H standards. In this part the mo- dulator performance characteristics and its simulation and laboratory measurements are presented with focus on typical DVB-T/H broadcasting scenario – large SFN network for fixed reception. The paper deals with the COFDM modulator imperfections and I/Q errors influence on the DVB-T/H signals and the related I/Q constellation analysis. Impact of the modulator imperfections on Modulation Error Rate from I/Q constellation and Bit Fig. 1. DVB-T/H modulator with I/Q errors and imperfections Error Rates before and after Viterbi decoding in DVB-T/H (illustration comes from [2]). signal decoding are evaluated and discussed. modulator and transmitter parameters. A lower quality signal of the modulator can be produced by Crest factor limitation, intermodulation, noise, Keywords I/Q errors and interferers [1]. To avoid effects of the terrestrial transmission link and modulator imperfections, I/Q modulator, I/Q modulation error, Amplitude DVB-T/H use COFDM (Coded Orthogonal Frequency Imbalance, Phase Error, Carrier Suppression, Division Multiplex).
