Digital signal processing: preserves information, increases flexibility, reduces cost.

•Traditional approach:

•Hardware signal processing and trigger generation before digitization.

•Information preserved:

•Pulse height

•Integrated charge

•Time of arrival

•Different detectors require different signal processing hardware.

•DSP approach:

•Digitization first, followed by signal processing either in the processor, off-line, or both.

•Information preserved is determined by the user (e.g. entire waveform, pulse height, time of arrival)
