SNR (s n) is the ratio of the average power of the transmission signal to the average power of the noise. Carrier voltage (C n) refers to the ratio of the average power of the modulated signal to the average power of the supplementary noise. They are usually calculated in logarithm mode, in dB. The signal-to-noi
