Match the columns.

Match List-I with List-II.

List –I (Counter)	List – II (Uses/working)
A.	N-bit Ring Counter	I.	Uses universal clock
B.	Synchronous Counter	II.	Counts exactly N states
C.	Asynchronous Counter	III.	Counts 0 to 9
D.	Decimal Counter	IV.	Main clock is applied to first flip-flop only

Choose the correct answer from the options given below:

Correct option is C

· N-bit Ring Counter: This counter cycles through exactly N states, where each state corresponds to a unique bit pattern.
· Synchronous Counter: It operates with a universal clock signal, ensuring that all flip-flops in the counter update simultaneously.
· Asynchronous Counter: In this counter, the main clock is only applied to the first flip-flop, and the subsequent flip-flops receive their clocks from the preceding flip-flop.
· Decimal Counter: It counts from 0 to 9, commonly used in decimal counting applications.
Information Booster:
· Ring Counter: Cycles through a fixed set of states, typically used in sequence generating applications.
· Synchronous Counter: Ensures precise timing across all stages due to the universal clock.
· Asynchronous Counter: Operates with ripple carry, often resulting in a slight delay across bits.
· Decimal Counter: Also known as a BCD counter, limiting counting to decimal values.
