Found in a 1965 General Electric datasheet, this low frequency circuit divides the frequency of a 20 kHz signal by 10, thus obtaining a 200 Hz signal.
This high Q “rejector” or notch filter rejects signals whose frequencies are in the range...
This circuit was found in documentation from the 90's, having an LC compensation network. The...
This two-transistor circuit was found in the January 1994 issue of Electronics Now magazine....
