How the asynchronous loading of the
counter is done?
|
|
The asynchronous loading of the counter is done by
initial state is loaded using direct SET and direct CLEAR inputs on the flip
flops.
|
37
|
How the synchronous loading of the
counter is done?
|
|
The synchronous loading of the counter is done by
occurrence of clock pulse using JK inputs on the flip flops.
|

|
How many bits are counted by N – bit
ring counter and N – bit ripple counter?
OR
Why the ripple counter is economical
to that of the ring counter?
|
|
The N – bit
ring counter count only n bits whereas the N – bit ripple counter counts 2n
bits therefore the ripple counter is economical to that of the ring counter.
|

counter as compared to ripple counter.
|
|
Advantages of ring counter over ripple counter
|
