Obtain the resonant frequency and Q-factor of a series LCR circuit with `L = 3.0 H, C = 27 muF, and R = 7.4 Omega`. It is desired to improve the sharpness of the resonance of the circuit by reducing its ‘full width at half maximum’ by a factor of 2. Suggest a suitable way.

A

AND gate

B

NAND gate

C

NOR gate

D

OR gate

Text Solution

Verified by Experts

The correct Answer is:
C

NOR gate
Suppose A and B are input and Y is output,

`therefore Y_(1)=(bar(A+B))=barA*barB` (According to De-morgan.s law)
`Y_(2)=barY_(1)=(bar(barA*barB))=barbarA+barbarB=A+B`
`therefore Y=barY_(2)=(bar(A+B))`
Therefore, the given circuit is of the NOR gate.
