Command window is not visible properly

[@arianzaddahesh3676]

Much obliged sir

[@VenkatPasupuleti27]

Thank You !

[@asadrao5147]

[@harshalchavan_5917]

Sir please send the code

[@baselalhayek2550]

What is f1 and f2

[@VenkatPasupuleti27]

f1 is message signal frequency, f2 is not used. Just mentioned to give different input frequency

[@usmaniftikhar4711]

Sir plz give code for ppm

[@charupandey125]

Can i get the codes?

[@VenkatPasupuleti27]

clc; clear all; close all; fc=1000; fs=10000; fm=200; t=0:1/fs:(2/fm-1/fs); mt=0.4*sin(2*pi*fm*t)+0.5; st=modulate(mt,fc,fs,'PWM'); dt=demod(st,fc,fs,'PWM'); figure subplot(3,1,1); plot(mt,'r'); title('message signal'); xlabel('timeperiod'); ylabel('amplitude'); axis([0 50 0 1]) subplot(3,1,2); plot(st,'r'); title('modulated signal'); xlabel('timeperiod'); ylabel('amplitude'); axis([0 500 -0.2 1.2]) subplot(3,1,3); plot(dt,'r'); title('demodulated signal'); xlabel('timeperiod'); ylabel('amplitude'); axis([0 50 0 1])
