Typical Application and Test Circuit
Note S
This figure shows the LM1596 used as a single sideband (SSB) suppressed carrier demodulator (product detector) The carrier signal is applied to the carrier input
port with sufficient amplitude for switching operation A carrier input level of 300 mVrms is optimum The composite SSB signal is applied to the signal input port
with an amplitude of 5 0 to 500 mVrms All output signal components except the desired demodulated audio are filtered out so that an offset adjustment is not
required This circuit may also be used as an AM detector by applying composite and carrier signals in the same manner as described for product detector
