Abstract
In sampled data digital telemetry systems the signal-to-noise ratio (SNR) is typically derived as a function of the moments of the digitized input stream (e.g., the receiver output). This analog-to-digital conversion process is itself an additional noise source known as the “quantization” noise. Thus a digitally measured SNR will only approximately represent the SNR of the analog input signal. This report presents a procedure (Sheppard’s corrections) for correcting moments of any order for this quantization effect.
