Signal averaging is a signal processing technique applied in the time domain, intended to increase the strength of a signal relative to noise that is obscuring it. By averaging a set of replicate measurements, the signal-to-noise ratio (SNR) will be increased, ideally in proportion to the square root of the number of measurements. Webvoltage. This allows them to accurately measure the average power of most signals, including modulated, multi-tone, or pulsed signals. For unmodulated signals (i.e., continuous wave or CW), sensors like Anritu’s MA247xD and MA244xD series can operate in all three diode ranges (linear, transition, and square-law) to determine average power.
