Answer 3

this is an example for SUPERPOSITION

clc
clear
close

A = 10;
f = 200;
t = 0:0.0001:0.01;
theta = 0;
w = 360*f;

y1 = A*sind (w*t + theta);

plot (t,y1)
xlabel ('time (ms)');
ylabel ('y');
title ('Sinusoidal Wave')

hold on


A = 6;
f = 500;
t = 0:0.0001:0.01;
theta = 0;
w = 360*f;

y2 = A*sind (w*t + theta);

plot (t,y2)
xlabel ('Time (ms)');
ylabel ('y');
title ('sinusoidal wave')

hold on

A = 6;
f = 1000;
t = 0:0.0001:0.01;
theta = 0;
w = 360*f;

y3 = A*sind (w*t + theta);

plot (t,y3)
xlabel ('time (ms)');
ylabel ('y');
title ('Sinusoidal wave')

hold on

t = 0:0.0001:0.01;
y4 = y1 + y2 + y3;

plot (t,y4)
xlabel ('time (ms)');
ylabel ('superposition');
title ('Superpotition Graph')

grid on
