资料介绍

主要设计一种能够合成指定波形的信号波形发生电路,电路基于傅里叶合成,通过产生不同频率的正弦信号,将这些信号处理后送入加法电路可合成所需信号。主要由方波产生模块产生方波,分频与滤波模块对所得方波分频并滤成正弦波,放大模块对所得正弦波幅值进行调节,移相模块调整各频率正弦波相位,最终通过信号合成模块合成所需波形。

This paper mainly designs a signal waveform generating circuit that can synthesize designated waveform. Based on Fourier,it can produce various frequency sine signals. After processing, these sine signals can be synthesized designated signal through addition circuit. Among the circuit, the square wave generating module produces square - wave,and the square - wave is divided frequency and filtered into sine wave though frequency separating and filtering modules. After that, the amplifier module magnify the amplitude of the sine wave obtained. Then phaseshifting module adjusts the amplification of each frequency sine wave. Finally the signal waveform synthesis module synthesizes designated waveform with processed sine waves.
