Two Input or Gate

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.

Mounted on transparent covered base for easy demonstration. Diagram and two sockets are provided for use with some circuit. Thermistor is mounted above the base to avoid the damage from heat.

Mounted on transparent covered box. Diagram provide with three different color four mm sockets for easy identification of terminals.
