Counter Implementation/ Counter design Using JK flip flop. 

This video is on counter design for a binary sequence. it explains all the steps for counter design in detail. Before counter implementation, one should have basic idea about the flip flop, state transition table, and state transition diagram. After getting the transition table, KMap has been used to get the logical expressions. then the counter is designed using these logical expressions.
This video explains easiest and simple approach to design a binary counter.
Question: Design a counter to produce the following binary sequence (1, 4, 3, 5, 7, 6, 2, 1..). Use J-K flip-flops.
Steps to solve the question
Step 1 State Diagram
Step 2 Next state table
Step 3 Flip Flop Transition Table
Step 4 Circuit Transition Table
Step 5 Karnaugh Maps (KMAPs)
Step 6 Logical expression
Step 7. Counter Implementation
