The purpose of this laboratory is to familiarize you with the basic commands in MATLAB for signal generation and verify the generated signal.

Objectives

1.     Learn basic MATLAB commands and syntax, including help system.

2.     Use MATLAB ( from Citrix) to generate and plot different signals.

Assignments

1.  Generate and plot the signal x1(t) = 1+ sin (4pt), for t ranging from -1 to 1 in 0.001 increments. Use proper axes labels with title.

1. Generate and plot the function x2(t) = sin (30pt), for t ranging from -1 to 1 in 0.001 increments. Use proper axes labels with title.

1. Generate and plot the combination function x3(t) = x1(t)*x2(t) as above. Use proper axes labels with title.

1. Generate and plot the sum of two cosine waves  v1(t) = cos(20pt) and v2(t) = cos(22pt), for t ranging from -1 to 1 in 0.001 increments. Use proper axes labels with title. Let x4(t) =v1(t) +v2(t).

1. Generate and plot the signal represented by   x5(t) = e-0.1t sin (2t/3), for t ranging from 0 to 30 in 0.1 increments. Use proper axes labels with title.

6.    Generate and plot the signal represented by   x6(t) = sin (4pt)/ 4pt, for t ranging from -1 to 1 in 0.001 increments. Use proper axes labels with title

7.     Plot the function x7(t) = (1 - e -2t ) cos (60 pt). Use t from 0 to 0.25 in 0.001 increments. Use proper axes labels.

8.    Plot a discrete-time signal x[n] using the following commands:

>> n= -2: 6;

>> x=[ 0 0 1 2 1 0 -1 0 0];

>> stem(n,x);

>> xlabel('n');

>> ylabel('x[n]');

>> title (' Plot of a discrete-time Signal');

1. The force f(t) in newtons(N) in a certain industrial process increases with the square of time over a particular time interval and cab be expressed as

                       f(t) = 0.25 t2 .

     Use MATLAB to plot the function from t=0 to t= 10 s.

Write MATLAB Program codes and Comments on your observation about each signal plot.

Use help command for all MATLAB commands to know the detail.
