WebAug 4, 2024 · 1 Answer. A chopper by itself does not eliminate drift, a chopper and a highpass (or bandpass) filter eliminate drift. The point of "chopping" is to place the information bearing signal from being near dc having low frequency content to be at a convenient so-called carrier frequency (for a chopper the "carrier frequency" is the rate of … WebThe C-995-3 Chopper is designed with a phase-locked-loop control system, allows the chopping rate to also be synchronized to a user-supplied external clock ranging from 4 Hz to 500 Hz. The controller is then used to measure and display the frequency of the external clock. The C-995 optical chopping head is attached to the controller by means of ...
