Requires only one tuning pot to cover entire frequency range.Developed for use in tunable narrow-band audio amplifier. Article gives design equations.Depth of notch is greater than 50 dB. Doubling capacitor values changes tuning range to 355-1028 Hz, while cutting values in half gives range of 1340-4110 Hz.-C. Hall, Tunable RC Notch Filter, Ham Radio, Sept. 1975, p 16-20.
