L ljcox Well-Known Member Jul 16, 2004 #2 I have posted several items on the design of counters using JK flip flops. Try this one for example. https://www.electro-tech-online.com/threads/kwh-meter.8219/ Your K maps don't make sense. Read the above post and then ask questions if you don't understand it. You could also do a search using me as the author and flip flop as the subject to find my other posts. Len Last edited by a moderator: Dec 26, 2013
