PCI1713板卡驱动,VB编写,8个通道,每个通道500次采样,对采样数据处理,为稳定现场信号的不稳定性-PCI1713 device driver, VB preparation, eight channels, each channel 500 sampling, Sampling of data processing, signal to stabilize the scene of stability

信号采样与DSP信号处理，很详细的介绍了工程中处理此类信号的方法-The signal sampling and DSP signal processing is described in detail the works dealing with such signals

voice recording for computer calls and train the calls signal.sampling process will lead the trained data.

根据采样定理对信号采样，之后依据采样值恢复原信号。恢复的信号基本一致，验证性-Signal is sampled according to the sampling theorem, and then restore the original signal based on sampled values. Recovered signal basically the same, confirmatory
