What is coherent averaging?

Coherent averaging is used to recover the response to repetitively applied stimuli when that response is embedded in random noise, and when the signal/noise ratio is fractional.

What is digital averaging?

Signal averaging is a digital technique for separating a repetitive signal from noise without introducing signal distortion (Tompkins and Webster, 1981). This chapter describes the technique of signal averaging for increasing the signal-to-noise ratio and discusses several applications.
