ANS:C - 5

We can write this eq as AA'+AB'+BB'+BC' bcoz AA'=0 then again we simply this eq as A(A'+B')+B(B'+C').

We need 1NAND gate for A'+B'.
For A(A'+B') 1NAND.
For B'+C' 1NAND.
For B(B'+C') 1NAND.

FINALLY, FOR THAT EQ WE NEED ANOTHER NAND GATE totally 5NAND GATES.

ANS:D - NOR gate

If we take 2ips A=0, B=0 starting bubble means invertion of given values that means A=1, B=1 for these AND operation we can perform it gives 1 is the op.

Like that we sub all 01,10,11 the ops of these are 0,0,0 finally we get 1,0,0,0 this is like NOR operation so This symbol is equal to NOR gate.

ANS:D - fan-out

Fan in: the number of inputs that can be connected to a circuit.

Fan out:the number of inputs that can be connected to a specified output.

ANS:C - an AOI circuit

AOI means AND-OR-INVERT CIRCUIT.This circuit is implemented in the CMOS logic family.AOI perform one or more AND operation follwed by an OR opearation and Inversion.

ANS:A - AND-OR logic

Y = A&B + C&D

1st half block --> AND Logic.
2nd half block --> summation of AB and CD will be "1" when either both are "1" OR ANYONE of AB or CD is "1"

--> >=1 represent OR Logic.

ANS:C - inverter

If both inputs are connected means, 2 inputs are connected as 1 input to a NOR gate.

Then it acts like an inverter.
