Description: Integrated use of theoretical knowledge of digital signal processing in spectrum analysis and filter design, the corresponding conclusions through theoretical derivation, using matlab as a development tool for computer practice, so as to deepen the understanding of knowledge, concept is established. Recording a voice signal, to determine the sampling frequency Draw the sample get signal time domain waveform and spectrum graph Add noise on speech processing (random noise, periodic noise, etc.), using the window function method (or equal-ripple best approximation method and bilinear transformation method of filter design, draw the filter frequency response The signal gathers which is then used to design the filter to filter for denoising processing, draw out the noise of signal waveform and its frequency spectrum And played back.
