I am trying to develop an intercom that sends out audio signals of 4Kz
bandwidth (three different channels through the same cable/wire.
(Prior to making that, I am actually trying to simulate that on a
computer so as to reduce the cost). I have double side band
suppressed carrier (DSSC) band modulator circuit (MC/LC 1496
modulator), a summer circuit and single side band suppressed carrier
(SSSC) demodulator circuit. But I don’t have the filter circuit
that converts double side band signal to single side band and also I
also don’t have the circuit for filtering out different channels
from the wire. (Since it’s in a simulator, I have quite wide
range of carrier frequencies by simply changing the parameters).
Would you please help me with a filter circuit (4Kz) bandwidth and do
tell me if i am missing anything.
