- function u=am_mod(a,m,ts,fc)
- % u=am_mod(a,m,ts,fc)
- %AM_MOD takes signal m sampled at ts and carrier
- % freq. fc as input and returns the AM modulated
- % signal. "a" is the modulation index
- % and ts << 1/2fc.
- t=[0:length(m)-1]*ts;
- c=cos(2*pi*fc.*t);
- m_n=m/max(abs(m));
- u=(1+a*m_n).*c;
