Answer 1

Answer:-

Gates are digital (two-state) circuits because the input and output singles are either low voltage (denotes 0) or high voltage (denotes 1).

Gates are called logic circuits because they can be analysed with Boolean algebra.

Three basic logic gates are :-

• Invertor (NOT Gate)

• OR Gate

• AND Gate

$\pink{\bigstar}$ $\large\underline{\boxed{\bf\green{Invertor \: Gate:-}}}$

• An Invertor gate is a gate with only one input signal and only one output signal.
• Output signal is always the output in input state.

$\pink{\bigstar}$ $\large\underline{\boxed{\bf\green{OR \: Gate:-}}}$

• In OR gate if any of the input signal is 1 then the output signal will be 1.

$\pink{\bigstar}$ $\large\underline{\boxed{\bf\green{AND \: Gate:-}}}$

• In AND gate when all the inputs are 1 (high) then the output will be 1.
• Else the Output will be 0(low).

Answer 2

Explanation:

Logic gates :

• It is the device which work on the same logical function.

• It having generally two input & one output.

• It bases on the binary system.

Types of logical gates :

• 1. AND GATE:

• 2. OR GATE:

• 3. NOT GATE:

• 4. NAND GATE:

• 5. NOR GATE:

• 6.XOR GATE:
