A Voltage-Controlled Active Low-Pass Filter,

Abstract

This report describes the design of a low-pass active filter of any desired order, in which the cutoff frequency is under the control of either: (a) A manual potentiometer, or (b) an active control potential. The cutoff frequency can be arranged to operate on a linear law with respect to the active control potential, and can articulate at a rapid rate. (Author)
