MATLAB program for Exponential wave signal Generation

Exponential Wave:

 An exponential signal is defined as

x(t)= A(e)^(a*t)                                                                                                                                                                          

Where both ‘A’ and ‘a’ real. If ‘a’ is positive the signal x (t) is a growing exponential and if ‘a’ is negative then the signal x (t) is a decaying exponential

Exponential Wave:

N=input ('Enter the duration of signal N= ');

a=input('Enter the scaling factor a=')

t=0:1:N-1;

y=exp(a*t);

stem(t,y);

title('Expontial Squence');

xlabel('Time Index');

ylabel('Amplitude');

Output waveform:

Enter the duration of signal N= 10

Enter the scaling factor a=0.3

a =    0.3000
