In some cases, this reduction of ripples is performed by controlling a voltage offset of an amplifier of said chopper amplifier arrangement. In other embodiments, a detection of ripples or a chopping of the chopper amplifier arrangement is at least temporarily disabled.

Tuning Fork Resonant Choppers – Photonics Online

The chopper operates at the natural resonant frequency established by the effective mass of the moving assembly and the spring constant of the tines. Chopping frequency ranges from 10 Hz to 6 KHz, apertures up to 15mm are practical in the lower frequencies (under 100 Hz), 0.5mm at 3 KHz and 0.2mm at 6 KHz.

Sampling (signal processing) – Wikipedia

The sampling frequency or sampling rate, f s, is the average number of samples obtained in one second (samples per second), thus f s = 1/T. Reconstructing a continuous function from samples is done by interpolation algorithms.
