What is a Tuned Radio Frequency (TRF) Receiver || How to Construct a Tuned Radio Frequency Receiver

Explains what is meant by a tuned radio frequency receiver, the working of various sections of the receiver and its functions. Briefly mention the different types of TRF IC chips that were available earlier. Also enumerate the various disadvantages of the TRF receiver. The demonstration shows how to construct a tuned radio frequency receiver using tuned circuits to tune to a specific frequency, radio frequency amplifiers to amplify the RF signals from the antenna, detect or demodulate the audio signal from the radio signal using a diode and amplify the audio signals using an audio power amplifier.
