Production of sound messages by a microphone in a radio station (studio).
1) Audio frequency generation.2) Generation of r.f. carrier wave.3) Modulation in a transmitter,b) 4) Transmitting antenna on a tower,c) Radio receiver,5) Receiving antenna,6) Tuning circuits,7) Detector (demodulator),8) Amplifier,9) Speaker.
Production of sound and modulated waves : In the studio, the music or song is converted into electrical signals using a microphone. These signals are in the audio frequency (a.f) range. An osillator produced suitable r.f. carrier wave.
Radio transmitter or modulator: The a.f. signal and r.f. waves are combined in the transmitter. The modulated (combined) waves are fed for an antenna fixed on a tower. This transmitting antenna broadcasts the modulated r.f. waves into space.
Radio Receiver: The aerial of a radio receiver receives the modulated waves transmitted by various radio stations. The tuning circuit inside the radio set selects only the desired signal. The detector circuits demodulates the modulated signals. Then the a.f. signal is fed to an amplifier. The amplified electric signals are fed to a speaker and converted into the music or song.

Non- Linear circuit It can be described as that circuit whose parameters change with voltage or current.
How do you use operational amplifier as differentiator and adder/subtractor. Fig. shows differentiator or differentiation amplifier. As its name implies, circuit performs mathe
Electrons travelling at right angles to a magnetic field experience a force of 8.3 x 10 -13 N when they are in a magnetic field of 6.2 x 10 -1 T. How fast are the electrons
Q. If the net force acting on an object is in the positive x-direction, the object moves only in the positive x-direction. It is not true, the object will accelerate only in the
