SpletMost simple tone control circuits use the simplest type of filter - resistance/ capacitance (RC) networks that provide a theoretical maximum slope of 6dB/ octave. Those using capacitors and inductors (real or simulated) can achieve far greater slopes, but are configured as band-pass or band-stop (depending on the pot position). Splet01. nov. 1980 · A single-chip integrated filter system, consisting of six switched-capacitor low- and high-pass filters, is described. It performs the separation of the high-group and low-group components of the incoming signal of a dual-tone multifrequency (DTMF) receiver, and the hard-limiting of the separated tones. SpletThe Elliptic filter has the steepest rolloff. For a simple anti-aliasing filter, often times a simple single-pole passive RC filter is acceptable. In other cases an active filter (i.e., using an op amp) works well. ...
