Signal Averaging
eXpert FPGA DSP Feature for CompuScope Digitizers

Signal averaging is a powerful method of improving the fidelity of noisy repetitive signals. The process consists of making multiple acquisitions of a repetitive waveform and averaging all acquisitions together. Any random noise is subsequently averaged to near zero, while the amplitude of the underlying repetitive signal remains unchanged. Using signal averaging, small signals can be extracted from a background of high-amplitude noise, which may even be larger than the actual signal itself.

Utilizing the eXpert Signal Averaging Firmware on a GaGe CompuScope Digitizer allows users to detect a small repetitive signal in a noisy environment by conducting rapid signal averaging completely on the digitizer’s onboard FPGA with absolutely no host system CPU loading.
