信号波形合成实验电路

摘要:本设计采用TI公司的NE555组成方波振荡电路产生10KHz的方波,将此方波分别经过中心频率分别为10K、30K及50K的有源带通滤波器实现分频与滤波,产生与各中心频率相同的正弦波。再经过移相电路与加法电路,最终合成近似方波和满足一定相位关系的三角波。

关键字:方波振荡电路,分频与滤波,移相,加法电路,三角波 Abstract:This design uses TI Corporation's NE555 composition square-wave oscillating circuit to have the 10KHz square-wave, this square-wave respectively after the center frequency respectively is 10K, 30K and the 50K active bandpass filter realizes the frequency division and the filter, produces with the various center frequency same sine wave. Again after the shift circuit and the adding circuit, synthesizes the approximate square-wave finally and satisfies certain phase relation the triangular wave.

Key words:Square-wave oscillator, frequency and filter, phase-shift circuit, addition, triangular wave
