Abstract
The development of a feedback network with a single component frequency control for selective audio frequency amplifiers is described. When used in conjunction with an adjustable over‐all feedback factor, the network has allowed the design of a 105‐dB amplifier with bandwidths of 30, 100, and 400 cps, tunable over a frequency range of 400–6500 cps. The design criteria are readily applied to other frequencies and bandwidths.Keywords
