fm receiver seminar

This is the most simple fm receiver with good performances that works great even if the sensitivity is not too high. The working principle of this radio receiver may seem a little unusual. It is made of an oscillator (T2 and T3) that is synchronized with the received frequency of T1 which works as a broadband preamplifier in VHF range.

How does the fm receiver works

The oscillator is adjusted between 87 108 MHz with C5. Because of the synchronization, the oscillator output will have the same frequency deviation as the re ....etc

LASER TORCH BASED VOICE TRANSMITTER AND RECEIVER
Using this circuit you can communicate with your neighbors wirelessly. Instead of RF signals, light from a laser torch is used as the carrier in the circuit. The laser torch can transmit light up to a distance of about 500 meters. The phototransistor of the receiver must be accurately oriented towards the laser beam from the torch. If there is any obstruction in the path of the laser beam, no sound will be heard from the receiver. The transmitter circuit (Fig. 1) comprises c ....etc

free download superheterodyne receiver seminar report

Superheterodyne is a contraction of supersonic heterodyne, where supersonic indicates frequencies above the range of human hearing. The word heterodyne is derived from the Greek roots hetero- different, and -dyne power. In radio applications the term derives from the heterodyne detector pioneered by Canadian inventor Reginald Fessenden in 1905, describing his proposed method of producing an audible signal from the Morse code transmissions of the new continuous wave transmitters. ....etc
