I need to add 5% noise to my signal (amplitude of noise = 0.05* signal amplitude) using "randn" as:
signal_noisy=signal+0.5*randn(signal) % (is it correct?)
is the genereated noise, whight gussion one?!
if I want to use "awgn" is it correct to say in this case SNR=13 ???
I realy appriciate your help here
