Question

Find the period of: a) x(t) = 3*sin(20πt) and b) x(t)=6*sin(40πt+π)

Answer 1

Answer:

CO DE:

clear all;

t = 0:1e-3 :400e-3;

y0 = 3 *cos(20*p i  *t)-2*s in(30*pi*t);

fig  u re(1),

sub  plot(2,1,1),p lot(t,y0,'--');

xl a b el('t');y l a el('x(t)'),hold on

subplot(2,1,2),plot(t,y0,'--');

xl a be l('t');    y l a bel ('x(t)'),hold on

on:

hope it helps u
