The picture shows the double-sideband suppressed-carrier (DSBSC) signal circuit generated by the LM-1496. When it is followed by connecting the IF-stage with the band-pass filter of the band 2.5 ~ 3kHz, the circuit can also produce single-sideband signal. Usually,carrier signal Vcis generated by a crystal generates and the audio level generates modulated signals Vm through microphone input end or the audio oscillator. J. Carl • Yoshev has ever seen a circuit which is just like a signal generator / test equipment. This circuit can be used for amateur radio and the Navy HF-SSB’s radio transceiver.
