FFT and IFFT for 16-bits wave, you can use this instead of convolution calculate, input samples must be 2^n. If its not 2^n samples just stuff zero in last array. I already make it to C++ class you can new a calss and do it easy

用VC++MFC编写的上位机软件，它可以通过rs232串口接收下位机发送来的数据并实时显示，还可以对波形作频率幅度检测，还可以做更多普通示波器做的事情。-Prepared using VC++MFC software, it can be through the RS232serial port to receive the client to send data and display in real time, but also on the wave frequency amplitude
