Single Side Band Suppressed Carrier (SSB - SC) - Modulation Scilab code using hilbert transform

Aim: Write scilab code to get the SSB-SC Amplitude Modulation using hilbert transform

Requirements: PC with Scilab software

Program:

Clf
F1=input(‘enter the baseband signal frequency’)
F2=input(‘enter the carrier signal frequency’)
Fs=input(‘enter the sampling frequency’)
T=input(‘enter the duration of signal’)
t=0:T/Fs:T
m=cos(2*%pi*F1*t)        // use %pi=&pi for MATLAB
c=cos(2*%pi*F2*t)
dsb1=m.*c
m1=imag(hilbert(m))      
c1=imag(hilbert(c))
dsb2=m1.*c1
su=dsb1-dsb2
sa=dsb1+dsb2
