A tuned radio frequency receiver (or TRF receiver) is a form of radio receiver which is made using a number of tuned radio frequency (RF) amplifier stages accompanied by a detector (demodulator) circuit to draw out the audio signal, along with an audio frequency amplifier for amplifying the extracted audio into a loudspeaker. This kind […]

Tuned Infrared (IR) Detector Circuit
The article is a continuation of the earlier post where we tried to find a solution for creating unique infrared IDs for trains in a model locomotive system. Here I have explained the application in detail and learn how it may be possible to successfully implement the idea using tuned IR detector circuits. The idea […]
