LOGIC GATES

Basic Logic Gate

Fig, shows a logic gate circuit with two input A and B and the output C. The voltage wave form of A, B and C are as shown in Fig.The logic gate circuit is

The following shows a logic gate circuit with two inputs A and B and the output C. The voltage waveforms of A, B and C are as shown below. The logic circuit gate is

The following figure shows a logic gate circuit with two inputs A and B and the output C. The voltage waveforms of A, B and C are as shown below. The logic circuit gate is

The Fig shown input waveforms A and B to a logic gate. Draw the output waveform for an OR gate. Write the truth table for this logic gate and draw its logic symbol.

What is logic gate? Distinguish between AND and OR gates.
