OBJECTIVE: Basic Logic Gates Apparatus has been designed to verify the truth tables of the following Gates:

I) AND Gate (IC 7408)

Ii) OR Gate (IC 7432)

iii) EX-OR Gate (IC 7486)

iv) NAND Gate (IC 7400)

v) NOR Gate (IC 7402)

vi) EX-NOR Gate (EX-OR + NOT Gate)

The Instrument Comprises of the Following Built In Parts:

1. Fixed output DC Regulated power supply of 5VDC.

2. Two logic ‘0’ and two logic ‘1’ inputs with output on sockets are provided on the front panel.

3. Two LED output indicator is provided on the front panel to observe the output status.

4. The symbols of each Gate are printed on the front panel and connections for input and output are brought on sockets. All the IC’s are mounted behind the panel.
