Audio Outputs
Both right and left channels have a stereo output for the
TV and VCR SCART. The monaural output, which is a
mix of the TV right and left channels, drives the RF
modulator, RF_MONO_OUT. The monaural mixer, a
resistor summer, attenuates the amplitude of each of
the two signals by 6dB. A 12.54dB gain block follows
the monaural mixer. If the left and right audio channels
were completely uncorrelated, then a 9.54dB gain
block is used. See Figures 4 and 5 for the functional
diagram of the audio section.
Clickless Switching
The TV channel incorporates a zero-crossing detect
(ZCD) circuit that minimizes click noise due to abrupt
signal level changes that occur when switching
between audio signals at an arbitrary moment.
