SSB-SC Modulation & Demodulation SA-233

Listing ID #3524554

SSB-SC Modulation - The circuit has two Balance modulators wired using IC 1496, two 900 RC Phase shift networks and OP-AMP IC 741 as summing amplifier. The external modulating signal and carrier signal are applied as an inputs directly to one Balance modulator and through 900 RC phase shifter to another Balance modulator to provide Balance modulator output which after summing network provides SSB-SC AM Balance modulator output. Maximum modulating frequency 10KHz, Maximum carrier frequency 100KHz, Built-in fixed DC ±12V/500mA Power supply and maximum test points.
SSB-SC Demodulation - The circuit uses IC 1496 wired with RC components and filter network as a SSB-SC Balance Demodulator to provide the demodulated AF output for the applied SSB-SC input. Maximum modulating frequency 10KHz, Maximum carrier frequency 100KHz, Bandwidth 3KHz, Built-in fixed DC +12V/500mA Power supply and maximum test points. Sine wave signal generators (2Nos) variable upto 100KHz frequency and 10Vpp amplitude.
Objectives :

• To study the SSB-SC Balanced Modulator circuit. To observe the single side band output with a suppressed carrier signal. To observe and note the change in SSB output w.r.t. change in modulating & carrier signal.
•  To study the SSB-SC AM Balanced Demodulator circuit. To observe and note the change in Demodulated output w.r.t. change in modulating. To observe the change in the demodulated w.r.t. change in carrier signal.
