WebThe formula for calculating the signal-to-noise ratio is snr=10*log10 (eb./no) To sum up, the SNR and eb/n0 are used to denote the ratio of useful and interfering signals to measure … Webr = snr(x) returns the SNR in decibels relative to the carrier (dBc) of a real-valued sinusoidal input signal x.The SNR is determined using a modified periodogram of the same length as the input. The modified periodogram uses a Kaiser window with β = 38.The result excludes the power of the first six harmonics, including the fundamental.
