buddieee . .. do you have to do that in the course elctronics II, i mean the upper division elective . ..  we have to take matlab ... that what i took but we didnt do the wave functions that displays graph cause of limited time . . but when you open the matlab . .. just use the help button .  that gives you a lot of what you want

Here U go dude: clear all; close all; clc; % import a auio sample [y,Fs,nbit]=wavread('your_audio.wav'); % extract left channel only left=y(:,1); % calculate the time scale Ts=1/Fs; [nsamples,c]=size(y); tscale=0:Ts:(nsamples-1)*Ts; %plot left and right channel in time domain plot(tscale,left,'r'); xlabel('Time (sec)'); ylabel('Amplitude'); %compute the FFT with the proper sampling frequency fmax=Fs; %how many points the FFT must be computed on? N=nsamples; tscale=0:Ts:(N-1)*Ts; %N=number of FFT points: % change it and test the different resolution fscale=linspace(0,fmax/2,floor(N/2)); spectrum=fft(left,N); %plot the spectrum of the signal using the appropriate % frequency scale and module of the coefficients %plot the magnitude figure(2); plot(fscale,abs((spectrum(1:length(fscale))))); xlabel('Frequency Hz') ylabel('Module')

ha ha.. I feel sorry for people coming here seeking someone to do their assignments for them. A little help/hits are fine but getting someone else to do it bothers me. You should just drop out of school if you are not prepared to spend time learning.

JHAPALIKETO, at least appreciate the work done for you

Dude ! somewhere in the code just write that "I have cheated in this assignment". I bet, this guy will submit as it is and he will be caught. haha
