Methods:The DSB- signal is produced in a circuit that is composed of a single chip VCO(MC16 48) ,a single chip function generater (MC 80 38) and a single chip analog m ultiplicator (MC 1496 ) and gives its output through a L C resonance circuit.

• 方法 :采用单片压控振荡器 MC16 48；函数发生器 MC80 38和单片集成模拟乘法器 MC1496组成载波抑制调幅电路 ；输出采用 L C谐振网络 .
