Create a file named “toneA.m” with the following MATLAB code:
clear all
Fs=5000;
Ts=1/Fs;
t=[0:Ts:0.4];
F_A=440; %Frequency of note A is 440 Hz
A=sin(2*pi*F_A*t);
sound(A,Fs);
Type toneA at the command line and then answer the following:
(a) What is the time duration of A?
(b) How many elements are there in A?
(c) Modify toneA.m by changing “Fs=5000” to “Fs=10000”. Can you hear any
difference?
(d)
Create a file named “tone.m” with the following MATLAB code:
function x = tone(frequency, observation_length);
% x=tone(frequency, observation_length) is used to generate
% a sinusoidal signal x with frequency and observation
% length specified in the arguments.
fs = 5000;
Ts = 1/fs;
t = [0:Ts:observation_length];
x = cos(2*pi*frequency*t);
Note that tone is a user-defined MATLAB function. Try the following commands:
help tone and y=tone(20,0.5). What are the uses of these two commands?

You are given a finite step function xt=-1 0<t<4 1 4<t<8. Hand calculate the FS coefficients of x(t) by assuming half- range expansion, for each case below. Modify the code below to approximate x(t) by cosine series only (This is even-half range expansion). Modify the below code and plot the approximation showing its steps changing by included number of FS terms in the approximation. Modify the code below to approximate x(t) by sine series only (This is odd-half range expansion).. Modify...
