用LabVIEW实现对输入音频滤波达到降噪效果(LabVIEW filter of audio signal)

说明：  基于labview的modus通信，接受和发送数据，产生报文(digital received and sent)

1．采用Labview设计一虚拟函数信号发生器， 通过数据采集卡输出波形信号，调节信号的相关参数，可观察示波器上波形的变化情况。 ⑴ 以NI MyDAQ数据采集卡作为输出接口； ⑵ 数据采集卡输出多种信号，至少完成三种波形：正弦波、三角波、方波(可调占空比)的输出，同时前面板上显示各输出波形； ⑶ 频率、幅值、初相位、直流偏移量和方波的占空比（0～100 ）等参数可以通过前面板控件调节。 ⑷ 前面板可显示输出波形。(1. Labview design using a virtual function signal generator, data acquisition card output waveform signal, adjust the relevant parameters of the signal can be observed on an oscilloscope waveform changes. ⑴ with NI MyDAQ data acquisition card as output interface ⑵ data acquisition card output a variety of signals, to complete at least three waveforms: sine wave output, triangle wave, square wave (adjustable duty cycle), while each of the output waveform is displayed on the front panel ⑶ frequency, amplitude, initial phase, the DC offset and duty cycle square wave (0 to 100 ) and other parameters via the front panel controls to adjust. ⑷ output waveform can be displayed on the front panel.)

I was suprised LabVIEW didn t had the CRC32. So I made it, http://en.wikipedia....edundancy_check, http://www.ietf.org/rfc/rfc1952.txt. It can take a array of U32, one element of U32 or a string. When needed I can create more CRC checks, CRC8, CRC16, etc... but CRC32 is the most used one I readed.
