Regenerative receivers require fewer components than other types of receiver circuit, such as the TRF and superheterodyne. The circuit's advantage was that it got much more amplification (gain) out of the expensive vacuum tubes , thus reducing the number of tubes required and therefore the cost of a receiver.

Double tuned Superheterodyne receivers usually contain double tuned circuits (sets of two loosely coupled circuits) as filters in IF receiver - this is because such a filter has almost flat band instead a ...

The reflex receiver should not be confused with a regenerative receiver, in which the same signal is fed back from the output of the amplifier to its input. In the reflex circuit it is only the audio extracted by the demodulator which is added to the amplifier input, so there are two separate signals at different frequencies passing through the ...
English: Block diagram of a regenerative radio receiver, a type of radio receiver widely used before World War 2. It consists of a tuned circuit that serves as a bandpass filter to select the desired radio signal out of all the signals picked up by the antenna, and a combined amplifier-detector to increase the power of the signal and extract the audio modulation (sound) signal from from the ...

English: Single vacuum tube Armstrong regenerative receiver circuit, invented in 1913 by American engineer Edwin Armstrong when he was a 22 year old college student. It was widely used until the 1930s when it was replaced by TRF and superheterodyne receivers. In the regenerative receiver, the gain of the tube is increased by feeding back some ...
