A Variable Bandwidth Constant K Filter.
Abstract
The problem consisted of designing a variable bandwidth constant gain filter for use with a superheterodyne pulse receiver capable of receiving ten microsecond and longer pulses. The desired results were achieved by electronically varying the shunt impedance of a three pole constant K filter 'T' section. This solution introduced the additional problem of designing a very low output impedance amplifier. A high gain feedback cathode follower is analyzed and designed to meet this problem. The operational characteristics of the variable bandwidth filter and the transient analysis of a constant K filter are included. (Author)
