适用范围：1.1 This standard ( Part 7 ) covers methods of measurement for parameters relating to fidelity of television receivers, namely:a) Modulation frequency/response characteristic, luminance and chrominance channel;b) Linear waveform response luminance and chrominance channel;c) Black level and its stability;d) dc component distortion luminance channel;e) dc component distortion, colour difference signal;f) dc component distortion, primary colour si gnal;g) Errors of chrominance signal demodulation angle;h) Effects of phase distortion on incoming signal for small picture areas;j) Luminance/chrominance delay inequality;k) G-4 signal matrixing error;m) Primary colour signal matrixing error;n) Spurious line sequential effects; andp) Line time non-linearity.1.2 This standard (Part 7 ) shall be read in conjunction with IS : 4545 ( Part 1 ) - 1983*.
