说明：  数字信号处理课程设计程序，实现频分复用，低通带通高通滤波器进行滤波。(Digital Signal Processing design process, to achieve frequency division multiplexing, low-pass band-pass filter high-pass filter.)

说明：  11电平的MMC的脉冲触发控制方法，含均压控制。(11 level MMC pulse trigger control method, including voltage sharing control.)

Code for denoising images. This code differs from standard wavelet denoising techniques in that it uses non-orthogonal wavelets, and unlike existing techniques, ensures that phase information is preserved in the image. Phase information is of crucial importance to human visual perception. Also, this code does have an effective way of determining threshold levels automatically. (Code for denoising images.
