music
- 在程序中用一般的MUSIC方法估计了信号的频谱,从两图中可看出在信号各频率处,频谱的峰值较大,故能明显的与噪声相区别,可在一定程度上避免在信号幅度较小时信号被噪声淹没的情况。-MUSIC method general procedures used to estimate the spectrum of the signal, it can be seen from the two graphs in the signal at each frequency of the spectrum pe
MATLAB
- 程序1:周期信号(方波)的展开 程序2:用图形表示DSB调制波形及其包络线 程序3:通过傅里叶变换找出被随机信号淹没的信号频率 程序4:DSB-AM 双边带幅度调制和解调 程序5:AM调制和解调-Procedure 1: periodic signal (square wave) Program 2: graph DSB modulation waveform and its envelope Application 3: through the Fourier tran
MATLAB-FFT
- 该段代码能实现找出隐藏或淹没在噪声时域信号中信号的频率成分。用FFT对试验数据进行谱分析,指出数据包含的频率成份。-One use FFT is to find hidden or submerged in the time domain signal noise frequency components of the signal. Test data with FFT spectrum analysis, pointed out that the data contained in freq
