filtermusic
- 一个GUI，低通滤波器，可以滤除音频信号的噪声部分，参数可以自己设定。基本原理采用多种不同滤波器进行比较-A GUI, low-pass filter, to filter out the noise part of the audio signal, the parameter can be set. The basic principles of using a variety of different filters are compared
DSPProjectFilteringNoise
- This a Digital Signal Processing project that filter a courrupted signal by blue noise using Low Pass Filter. Several LPF designs is included in the code. -This is a Digital Signal Processing project that filter a courrupted signal by blue noise usin
Project2LPF
- Create a 512-length signal then low-pass filter the signal with the filter
Waveletdecomposition
- This routine performs a 1-D Periodic Orthogonal Wavelet decomposition. It also performs the row decomposition component of a 2-D wavelet transform. An input signal x[n] is low pass and high pass filtered and the resulting signals decimated by factor
filter_test

winsinc
- The windowed sinc filter uses the inverse fourier transform of ideal low - pass filter frequency response. The Inverse transform of the ideal low - pass response is the sinc function (sinx/x). The inverse fourier transform of the required frequency r
movavg
- A moving average filter averages a number of input samples and produce a single output sample. This averaging action removes the high frequency components present in the signal. Moving average filters are normally used as low pass filters. In recursi
