Answer 1

$\huge\bold\red{answer}$

1)The AND gate is a basic digital logic gate that implements logical conjunction (∧) from mathematical logic – it behaves according to the truth table above. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1).

2)The three types of configurations are Common Base, Common Emitter and Common Collector configurations. In every configuration, the emitter junction is forward biased and the collector junction is reverse biased.

3)Solution. (i) Rising the strength of a weak signal is known as amplification and the device is called amplifier. (ii) Amplification factor is the ratio between output voltage to the input voltage. A=V0V+(i)

Answer 2

Answer:

1. A NAND gate is equivalent to an inverted-input OR gate.  An AND gate is equivalent to an inverted-input NOR gate. A NOR gate is equivalent to an inverted-input AND gate. An OR gate is equivalent to an inverted-input NAND gate.
