Location Certifications Pending. Download the 8B33 datasheet and block diagram. RMS, or Root Mean Square, is a key measurement of an AC signal. In practical terms, it is the equivalent DC signal that produces the same amount of heat in a given load. Therefore, it directly relates to signal power. For purely sinusoidal signals, the RMS value is the familiar peak amplitude divided by the square root of two. However, for signals comprised either of harmonics or of noncoherent content, this expression... (read more)Browse Signal Conditioners Datasheets for Dataforth Corporation
