frequency selective circuit

This paper describes that through extracting harmonic components of periodic signals of frequency selective circuit,computer simulation and measurement of cycle of fundamental triangle wave,3rd harmonic,5th harmonic,showes that results consistent with the theoretical analysis and validates the Fourier decomposition of the periodic signals.

通过选频电路对周期信号的谐波分量进行提取,并进行计算机仿真,测量了周期三角波的基波、3次谐波、5次谐波,结果与理论分析一致,验证了周期信号的傅里叶分解。

The core part of the circuit is differential and frequency selection.
