HOW TO GENERATE SINE, COSINE,RAMP,EXPONENTIAL,UNIT STEP AND UNIT IMPULSE SIGNALS USING MATLAB?

GENERATION OF SIGNALS:
                          

To write a program using MATLAB for the generation of signals like Sine sequence, Cosine sequence, Ramp sequence, Exponential sequence, Unit-step sequence and Unit-impulse sequence.

ALGORITHM:

SINE SEQUENCE:

 Step 1: Initialize the time period.
 Step 2: Design the function of sine wave.
 Step 3: Plot the sine sequence.
 Step 4: Display the output

COSINE SEQUENCE:

 Step 1: Initialize the time period.
 Step 2: Design the function of cosine wave.
 Step 3: Plot the cosine sequence.
 Step 4: Display the output

RAMP SEQUENCE:

 Step 1: Read the length of the ramp sequence.
 Step 2: Define the length of the ramp sequence.
 Step 3: Plot the ramp sequence using stem function.
 Step 4: Display the output.

EXPONENTIAL SEQUENCE:

 Step 1: Read the length of the exponential sequence.
 Step 2: Read its amplitude.
 Step 3: Plot the exponential sequence using stem function.
 Step 4: Display the output.

UNIT-STEP SEQUENCE:

 Step 1: Read the length of the unit-step sequence.
 Step 2: Plot the unit-step sequence.
 Step 3: Display the output.

UNIT-IMPULSE SEQUENCE:

 Step1: Read the length of the unit-impulse sequence.
 Step2: Plot the unit-impulse sequence.
 Step 3: Display the output.
