100-60-Zähler (Teiler durch 100 oder 60 mit 7490, 7400, 7410, 7404)

In contrast to lowpass or highpass filters, the gain of an all-pass filter remains constant over the range of frequencies at which it is used, but it does introduce a frequency- dependent phase shift. A number of all-pass filters may be cascaded to produce a phasing unit for use in electronic music. The phasing effect is produced by phase-shifting a signal and then summing the original and phase- shifted versions of the signal.
