Updated circuits:Improved AC Zero Crossing Detectors for Arduino. A zero-crossing detector is used to generate a sync pulse related to the AC voltage phase angle often used in power control circuits. Fig. 1 shows the relationship of a zero-crossing pulse to a sine wave. The pulse occurs at...

Zero-Crossing Detector Using 741IC -Waveforms Zero-crossing Detector as Time Marker Generator For an input sine wave, the output of the zero-crossing detector being a square wave, is further passed through an RC series circuit. This is shown in the figure below. Zero-Crossing Detector Using T...

might happen in different scale, which require the detector to be flexible, i.e. it can be easily tuned to detect intensity changes in different scale. (From my perspective, this relly makes no difference to an edge detector, although the idea might come earlier than famous edge detectors) ...
Echolocation calls are typically recorded using zero crossing detectors or full spectrum recorders at high sample rates, and the resulting recordings are then analyzed with software to display the frequency modulated sweeps common to many bat species. Identifying bat species from their echolocation calls...
Using two samples per symbol, the auto-covariance function of raised cosines is derived in closed form for one/two-dimensional signal constellations. The result is applied to the computation of the self-noise variance for feedback symbol-timing recovery with zero-crossing and Gardner detectors.DOI...
