基于模拟乘法器MC1496的频谱搬移电路设计

Design of Spectrum Moving Circuit Based on Analog Multiplier MC1496

模拟乘法器是信号频谱搬移电路设计中的核心运算芯片,文中采用MC1496实现信号的普通调幅、双边带调幅以及同步检波等频谱搬移操作。实验结果表明,该电路可有效实现信号的低电平调幅以及解调。

Analog multiplier is the core operation chip in the design of signal spectrum shift circuit.The design used MC1496 to realize the spectrum modulation operation such as common amplitude modulation,double sideband amplitude modulation and synchronous detection.The experimental results showed that the circuit can effectively realize the low level amplitude modulation and demodulation of the signal.
