Amplitude Modulation And Demodulation
Instrument is design to demonstrate the method to transmit signals via. Electromagnetic transmission. It is still used in radio system to transmit audio signal although it has lesser in popularity compared to FM (Frequency Modulation) due to its lower signal to noise ratio.
Technical Specification :-
1. I C based DC regulated Power Supply ±12 V / 500 mA.
2. Audio frequency 1 KHz / 0-2 Vpp for modulating signal 455 KHz / 2.5 Vpp approx. for Carrier Frequency.
Bridge Rectifier
Bridge Rectifier is made of four diodes connected in a bridge circuit. It is housed in a plastic moulded box. This bridge rectifier converts alternating current (AC) into direct current (DC). It provides the same output polarity for either input polarity. All the electronic devices require direct current, so bridge rectifiers are used inside the power supplies of almost all electronic equipment. For the easy understanding of the internal circuitry, the circuit diagram is printed on the box.
