Signal emitting system, signal conditioning module and signal conditioning method with adaptive current limiter for capacitive loads

Abstract

Adaptive current limiters for capacitive loads (and associated systems, devices, and methods) are disclosed herein. In one embodiment, a signal emitting system includes a signal processing unit, an amplifier, and an emitter. The signal processing unit can determine a delta limit based on (i) system parameters and (ii) a representative magnitude corresponding to a sample of a source signal, one or more samples of a conditioned signal, or a combination thereof. The signal processing unit can further determine a ratio of (i) the delta limit to (ii) a difference between a sample of the source signal and a previous sample of the source signal, and apply a lowpass filter to the source signal to obtain a filtered signal, with filter coefficients based on the ratio. The amplifier can generate an amplified signal based on the filtered signal, and the emitter can emit an output signal based on the amplified signal.
