Values of video and sound parameters can be decreased at V
The sound carrier trap can be bypassed by switching the I
The amplitude is 1.1 V (p-p).

S/N is the ratio of black-to-white amplitude to the noise voltage (RMS value measured on pin CVBS and tested at video black level,
‘quiet line’). Noise analyzer settings: B = 5 MHz, 200 kHz high-pass and sound carrier trap on. In case of S/N
with “ITU-T J.61” . Measurements taken for B/G standard.
The intercarrier output signal at pin SIOMAD can be calculated by the following formula taking into account the internal video signal with
1.1 V (p-p) as a reference:
