1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图
2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选
3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱
4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图- 1. Using Matlab to generate sine wave, square wave, and the white noise signal and displays each time-domain waveform 2. FFT transform, display each spectrum, where the sampling rate, frequency, data length optional 3. RMS to make maps of the three signals, power spectrum, as well as the number of rms Atlas 4. Restored by inverse Fourier transform IFFT signal and displays the time domain waveforms sinusoidal signal recovery
