Signal Recovery with PMTs
Application Note #4
Photon Counting, Lock-In Detection, or Signal Recovery Methods
Boxcar Averaging?
Which instrument is best suited for detecting signals from a
photomultiplier tube? The answer is based on many factors Gated Lock-in
Integrator Amplifier
including the signal intensity, the signal's time and frequency
distribution, and the various noise sources and their time 7
dependence and frequency distribution. 10

In general, the choice between boxcar averaging (gated
integration) and lock-in detection (phase sensitive detect |
