If we want to generate a signal that ...

Webthen I have edited the noise signal with the required power to achieve this SNR by normalizing it by the square root of its current power and multiplying it by the square root of the required power. The required power is derived from the formula of the SNR as : Power of noise = power of the cosine signal / 10^SNR/10;

WebIn the third function you're generating the output signal by adding the frequency components of each signal, but if it's just an additive gaussian noise, you could just add the noise to the signal.
