Hello to everyone. I created a histogram by separating the noise from the signals. now i want to calculate SNR. But how do I calculate the power of the noise? and what is the theoretical definition of the power of the noise? Thank you very much if you can enlighten me on this.

you can find the definition of the snr for example in the snr() documentation
