Electrical Noise and Mitigation: Part 1 - EE Times

WebAn analog signal is subject to electronic noise and distortion introduced by communication channels, recording and signal processing operations, which can progressively degrade the signal-to-noise ratio (SNR). As the signal is transmitted, copied, or processed, the unavoidable noise introduced in the signal path will accumulate as a generation ... WebNet gain/loss in a cascaded path can be calculated with simple addition/subtraction. Signal to noise ratio (in decibels) SNR dB = 10 log 10 (signal/noise) Note: “S/R” in the Shannon capacity formula is a normal ratio, not dB.
