Two Input Nand Gate

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

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.

Solderless Breadboard has 1680 tie points. Provided with 2 Terminal strips and 4 Distribution strips. Built in DC Regulated Power Supply. DC Supply ± 5V/ 1 Amp. 0 to ± 15V DC (Variable), 1 Amp. Built-in Function Generator. .

Bridge rectifier is designed with four LED’s internally arranged in bridge pattern fitted inside a plastic moulded case. Two LED’s are red and two LED’s are green. This device is used to demonstrate the functioning of a bridge rectifier, i.e., to convert alternating current (AC) into direct current (DC). Two yellow sockets are used for AC input. Two sockets, one red and one black, are used for DC output. For the easy understanding of the internal circuitry, the circuit diagram is printed on the box.
