IS 4545 : Part 7 : 1983 Methods of measurement on receivers for television broadcast transmissions: Part 7 Fidelity

1 Scope

1.1 This standard (Part 7) covers methods of measurement forparameters relating to fidelity of television receivers, namely:

a) Modulation frequency/response characteristic, luminance andchrominance 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 color signal;

g) Errors of chrominance signal demodulation angle;

h) Effects of phase distortion on incoming signal for smallpicture areas;

j) Luminance/chrominance delay inequality;

k) G-4 signal matrixing error;

m) Primary colour signal matrixing error;

n) Spurious line sequential effects; and

p) Line time non-linearity.
