基于PC声卡的双通道示波器设计（LabVIEW实现），从音频接口输入，带宽20k ，希望后来者使用其他接口如USB实现，提高带宽-PC sound card based dual-channel oscilloscope design (LabVIEW implementation), from the audio interface input bandwidth of 20k, then those who want to use other interfaces such as USB

将心电数据从文件中读取出来，并由声卡读入，从而发出心跳声，可将得到的声音作为模拟的心电信号-ECG data will be read out from the file, read by the sound card, which issued a heartbeat sound, the sound can be simulated ECG signal as

需要硬件支持才能当实际意义上的示波器用，但是模拟示波器的有matlab、LabVIEW等，可以直接测到声卡的波形。 -Hardware support to when the actual meaning of the oscilloscope, analog oscilloscope matlab, LabVIEW can directly measure the waveform of the sound card is required.
