English: Block diagram of a regenerative radio receiver, invented by Edwin Armstrong in 1912, is a type of radio receiver widely used up until the 1930s.. 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 ...
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 ...
A regenerative receiver, by contrast, could often provide adequate reception with the use of only one tube. In the 1930s the regenerative receiver was replaced by the superheterodyne circuit in commercial receivers due to the superheterodyne's superior performance and the falling cost of tubes.
Classical regenerative receiver using a single triode vacuum tube. The orientation of the "tickler" coil was carefully adjusted by the operator in order to vary the amount of positive feedback. The regenerative receiver also had its heyday at the time where adding an active element (vacuum tube) was considered costly. In order to increase the ...
Occasionally, a regenerative detector was used, to increase selectivity. Some TRF sets that were listened to with earphones didn't need an audio amplifier, but most sets had one to three transformer-coupled or RC-coupled audio amplifier stages to provide enough power to drive a loudspeaker. The schematic diagram shows a typical TRF receiver.
