Question 638
|
What is the maximum counting speed of a 4-bit binary counter which is composed of Flip-Flop with a propagation delay of 25ns ?
|
1MHz
|
|
|
10MHz
|
|
|
100MHz
|
|
|
4MHz
|
Question 638 Explanation:
Question is about frequency of the counter.
Frequency = 1/ Time
Binary counter is ripple counter where the output one flip flop is clock input to next flip flop.
So, maximum delay(time)= 4*25ns = 100 ns.
frequency= 1/100 ns
= 10 MHz.
Frequency = 1/ Time
Binary counter is ripple counter where the output one flip flop is clock input to next flip flop.
So, maximum delay(time)= 4*25ns = 100 ns.
frequency= 1/100 ns
= 10 MHz.
