三种方法编写多路选择器的VHDL源代码 分别使用if else ,select ,when 语句-three methods to prepare multiple choice of VHDL source code were used if else, select, when words

是基于FPGA的5620的数模转换芯片底层的应用程序，希望有用。(Is a digital-analog converter chip underlying the 5620 FPGA-based applications, and I hope useful.)

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.)
