Pick out which ones are for AND, NAND, and NOT gates, respectively.

To get an output Y = 1 from the circuit shown below, the input must be:

1. A=0 B=1 C=0

2. A=0 B=0 C=1

3. A=1 B=0 C=1

4. A=1 B=0 C=0

The following figure shows a logic gate circuit with two inputs \(A\) and \(B\), and the output \(Y\). The voltage waveforms of \(A,B\) and \(Y\) are as given.
 

The logic gate is:

The symbolic representation of four logic gates is as shown:

(i)		(ii)
(ii)		(iv)
