Counters

Question 1

Whats the Difference between Asynchronous , Synchronous Counters

What is the Modulus of a Counter?

Answer 1

Asynchronous, Doesnt have a common clock, all flipflops dont change at the same time due to propagation delays

Synchronous - All FLip Flops change on the Rising or falling edge of a common clock.

Modulus - Maximum of unique states through which the counter will sequence 2^n

Question 2

Draw a 2-Bit asynchronous Binary Counter using Jk Flip Flops (Block Diagrams)
Draw the Waveform for each of the output bits

Answer 2

Question 3

Draw a 3-Bit asynchronous Binary Counter using Jk Flip Flops (Block Diagrams)
Draw the Waveform for each of the output bits

Answer 3

Question 4

Draw a 2-Bit synchronous Binary Counter using Jk Flip Flops (Block Diagrams)
Draw the Waveform for each of the output bits

Answer 4

Question 5

Draw a 3-Bit synchronous Binary Counter using Jk Flip Flops (Block Diagrams)
Draw the Waveform for each of the output bits

Answer 5

Question 6

What is Propagation Delay

Show the Propagation Delay in a 3 Bit aSynchronous and 2 bit synchronous Counter

Answer 6

Delay in the change of the systems state, from when the input changed.

Asynchronous counters have
