The boxcar operation is defined by a trigger delay, a gate width and the number of trigger events (i.e., samples) that are averaged over in the buffer. The principle of operation can be understood as a two-step process: signal integration over the desired gate width and averaging the integrated signal over a defined amount of periods/trigger events WebMar 15, 2013 · I need to calculate time evolving PSD or Squared fft of a signal at certain frequency using a moving boxcar filter.
