Abstract
A selective feedback amplifier which is useful. at sub-audio frequencies is described .It is shown that has the Same characteristic as a simple resonant circuit and that the selectivity is improved by an increase in gain. The measurements on an actual amplifier are presented; they show close agreement with the theory.
