Question

State whether the following statements are true or false The circuit diagram of AND gate has  two input terminals and one output terminals.

Accepted Answer

The given statement is true.Concept- First, it is necessary to establish the AND gate's operating principle. Diodes must be used to construct the circuit diagram, and it is necessary to understand how the circuit operates.When all of the inputs are true, the output of an AND gate, which performs a logic and operation, is true. Depending on the need, it may have one output and two inputs or several inputs. Because the output is only high when all the inputs are high, it is known as an AND gate.The AND gate symbol is as follows. The input terminals are A and B, while the output is Q.The AND gate is an electrical circuit that uses diodes D1 and D2 as depicted in Fig. 2. Switches A and B are linked in series with the diodes in this circuit, and the output side of the circuit uses a resistor to act as a pull-down resistance to the ground. The output terminal is Y. Since it is a logic circuit, 0 denotes a zero input and 1 denotes a high input, or an ON status for the switches.The operating concept is that only a current will flow when power is applied to the circuit and switches A and B are closed, resulting in an output from the output terminal. The operation of the circuit is explained through four scenarios.Case(i) if  and  i.e. switches  and  are off, both diodes are in forward bias conditionand they conduct and hence the output will be zero, because the supply voltage will be dropped across load only. Therefore .Case(ii) if  and . When  and  is high, diode  is forward biased and diode is reverse biased. The diode D1 will now conduct due to forward biasing. Therefore, output .Case(iii) if  and .In this case, diode  will be conducting and hence the output .Case(iv)  and .Both of the diodes aren't conducting in this situation. There is no current flowing through the load since D1 and D2 are in the OFF condition. The output is the same voltage as the supply. Thus, the output is Y=1.Thus, only when both inputs A and B are high would the output be high.Hence, the given statement is true.
