Two Input Nor 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.

Trainer consisting of Power Supply of +5 V / ±12 V (each of 250 mA), Silicon, Germanium diodes, Zeners, PNP and NPN Transistors, FET, One speaker, 12 different values of carbon film resistances of ¼ W, ½ W and 1 W. 12 assorted values of capacitors from 100 pF to 1000 ?F, Integrated Circuit (IC) Base and IC 74LS00 1 No. each. LED, LDR, Photo diode, Solar Cell Logic Switches (4 No.) and LED Indicators (4 No.) etc., 2 mm Interconnection Leads -10 No. and Comprehensive User’s Manual

To study the OR digital logic gate and verification of the truth table.

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