Sinusoidal Signal

Matlab program to generate Sinusoidal Sequence/Signal in discrete and continuous form.

Matlab code

clear all; close all;

A=input('Enter the Amplitude of Sinewave=');
f=input('Enter the Frequency of Sinewave=');
n=input('Enter the Number of Cycle=');
Theta=input('Enter the Phase of Sinewave='); t=0:.01:n/f;

x=A*sin(2*pi*f*t+Theta); subplot(2,1,1);

plot(t,x);
