Db ratio's
WebJul 23, 2013 · The usual way is to attach a meaning of average power to the dB value. So use rms. For the noise you get 60 dB because randn has average power 1. For sin the theoretical rms value is 3 dB below the peak value, so you should get 37 dB, not 36 dB. Depending on the number of cycles of the sinusoid, your computed value might deviate … WebMar 20, 2024 · decibel (dB), unit for expressing the ratio between two physical quantities, usually amounts of acoustic or electric power, or for measuring the relative loudness of sounds. One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio.

Signal to noise ratio (SNR) is a local relation between a signal x [ n] and and noise w [ n] and is defined as: SNR = σ x 2 σ w 2. where σ x 2 and σ w 2 denote the powers of the discrete-time signal x [ n] and noise w [ n] respectively. Therefore if the signals involved are non-stationary of any sort, then the computed SNR will change ...
