Abstract

The noise suppression efficiency is experimentally investigated for discrete stroboscopic signal transformation providing 5–15 μV (RMS) sensitivity. A balanced comparator based on tunnel diodes is used as a clocked comparator. Ordinary and modified up-and-down methods are used to measure the instantaneous signal values. The experimental results are compared to the theoretical calculations.
