模拟信号合成电路的改良设计

Analog signal synthesis improvement design of the circuit

通过四阶巴特沃斯低通滤波器电路完成方波信号的分频,用放大衰减电路使信号复合方波和三角波合成时的幅值要求,接着经过移相,合成需要的方波。本系统对已有的信号合成电路进行了改良,使波形实际设计结果波形更加接近理论仿真效果。在一定理论仿真的基础上,本设计更过多的从实际调试角度出发研究信号合成电路。

By fourth order butterworth low-pass filter circuit to complete the square wave signal frequency, signal with attenuation circuit amplification composite square wave and triangular wave synthetic amplitude requirements, after phase shift, synthetic design requirements of the square wave. This system redesign of the existing signal synthesis circuit, the waveform design results waveform more close to the theoretical simulation result. On the basis of a certain theoretical simulation, the design is more too much from the actual signal synthesis circuit debugging perspective study.
