. The sound carrier frequencies (depending on the TV standard) are attenuated
by the integrated sound carrier traps (see Figs 13 to 18;
H (s)
is the absolute value of transfer function).
S/N
W
is the ratio of the black-to-white amplitude to the black level noise voltage (RMS value measured on pin CVBS).
B = 5 MHz weighted in accordance with “CCIR 567”
