From: HABIB AHSAN on 19 Mar 2010 01:14 for my project works i have to filter voice signals.how i can convert the signal into digital by matlab ? is that signal should be kept in WAV format in work file ? i want the full matlab code for different filters (low pass, high pass,band pass,band stop etc.) for FIR filter design in different window techniques immediately.

Use wavread() to read WAV files. You don't necessarily have to have your data in a WAV file. You can read a number of different file formats into MATLAB. 2.) Get the Signal Processing Toolbox There are a number of FIR filter routines

You need an ADC for that. > is that signal should be kept in WAV format in work file ? i want the full matlab code for different filters (low pass, high pass,band pass,band stop etc.) for FIR filter design in different window techniques immediately. Buy the filter design toolbox. Rune |
