add_noisem
把指定的噪声叠加到信号上去.有标准噪声库NOISEX-92,其中带有白噪声、办公室噪声、工厂噪声、汽车噪声、坦克噪声等等,在信号处理中往往需要把库中的噪声叠加到信号中去,而噪声的采样频率与纯信号的采样频率往往不一致,需要采样频率的校准。
(The specified noise superimposed to the signal up. Standard noise library NOISEX-92, with white noise, office noise, factory noise, car noise, tank noise in the signal processing often requires noise to be superimposed in the library The signal to noise of the sampling frequency and pure signal sampling frequency is often inconsistent sampling frequency of calibration.)

音频信号分析仪的FPGA源码
音频信号先经过由运放和电阻组成的50Ohm阻抗匹配电路以满足输入阻抗50 Ohm的系统要求,这样方便信号功率的计算。为了保证所处理的信号被不失真的采样,信号还要通过截止频率为10Khz的抗混叠低通滤波器。最后为了AD能正确的采样,信号还要通过信号抬高电路。
经过12位A/D转换芯片MAX144转换后的数字信号经由基于FPGA的NIOSII处理器进行FFT变换和处理,分析各个频率点的功率值,并将这些值显示在LCD上。
该源代码就是fft变换的源代码
