Hi carl
just looking at your HH project
with the channel 2 ( ic7b - which gets it timing from ic12a and ic12b) can we use that to somehow cancel ground noise... take the timing back just before the transmit pulse switches back on and lengthen the sample pulse of that. Say about 300us and switch on for aprox 100 or 200 us ????
What would happen if you had to samples there into the integrator that are of different sample pulse width.
maybe silly question...

hi

Fig. 16, produces a change in loudness
instead of frequency. IC7c chops the
output signal of IC8b, so the audio frequency
is constant and equal to the
master clock frequency. Keep in mind
that if the sample frequency is varied
(via R2), the audio frequency will follow.
They cannot be set independently in this locator...rajesh...
