Question

Design 3 bit ripple counter using JK flip flops?

Answer 1

$<b><i>$ I have to design 3-Bit Up Synchronous Counter Using JK Flip Flop counters.
The first one should count even numbers:
0-2-4-6-0
The second one should count odd numbers:
1-3-5-7-1
Execution Table For JK Flip Flop:
Q(n) Q(n+1) J K --------------- 0 0 0 X 0 1 1 X 1 0 X 1 1 1 X 0
First Question: Design a negative-edge-triggered synchronous counter with the form of operation: 0-2-4-6-0

Answer 2

4-Bit Ripple Counter. This circuit is a 4-bitbinary ripple counter. All the JK flip-flops are configured to toggle their state on a downward transition of their clock input, and the output of each flip-flop is fed into the next flip-flop's clock.
