Web(1) The maximum theoretical Signal-to-Noise Ratio (SNR) for an ADC can be determined based on the RMS quantization error determined above. If a Full-Scale (FS) sine wave is applied to the input of the ADC, the maximum theoretical SNR is determined by the equation below, where N is the resolution of the ADC in bits. Web19 May 2024 · SNR = Signal to Noise Ratio = Signal / Noise. SNR usually is given in "dB" and signal and noise are given in voltage_RMS. Thus in most cases: SNR (dB) = 20 x log (Signal_RMS / Noise_RMS) Signal_RMS .. is usually a single sinusoidal signal. Thus signal (RMS) in LSB = 2^ADC_bit_resolution / (2 x sqrt (2)) Example: for a 16 bit ADC: 23170 …

"Web12 Aug 2015 · THD +N (Total Harmonic Distortion plus Noise) THD is a measure of the affect a given component will have on the sound. A high rTHD figure (quoted as a percentage) will result in more colouration, therefore lower numbers are better. As with SNR, the THD of a well-designed modern hi-fi component will be kept to a minimum. " - Thd to snr
