WebFeb 1, 2008 · N RMS is the RMS noise voltage, typically weighted by a specified curve. In other words, baseband video SNR is the ratio of the peak-to-peak video signal, excluding sync, to the RMS noise within that signal. The noise is measured in a bandwidth defined by a combination of low-pass, high-pass and weighting filters. More on this in a moment. WebScabs in ear.
