摘要
A multi-pole, multi-zero design allowed realizing a %26quot;true%26quot; phase-shifter (not time-delayer) of flat frequency-response over more than three decades (30 Hz-100 kHz), which can be extended to higher frequencies or broader bands thanks to a modular design. Frequency-dependent optimization of a single resistance made also the gain flat to within few percents. The frequency-independent phase-shifter presented can find application in any experiment in which an action needs to be taken (e. g., a measurement needs to be performed) at a fixed phase-delay relative to an event, regardless of how rapidly the system rotates or oscillates.
