Abstract
The paper describes a selective amplifier having a frequency which is variable in steps between 1 and 1000 c/s, and a selectivity which can be set to values up to Q = 100. The amplifier is D.C. coupled and employs a twin-T net, shunted by a capacitor, as a selective net in the negative feedback line.This publication has 0 references indexed in Scilit:
