Design 3 bit ripple counter using JK flip flops?
I am not a Electronic Engineer, so probably any expert out there can correct me if I am thinking wrong.--------- As you can see below there is something common between JK and SR flipflop i.eThe JK flip-flop augments the behavior of the SR flip-flop by interpreting the S = R = 1 condition as a "flip" or toggle command. Specifically, the combination J = 1, K = 0 is a command to set the flip-flop; the combination J = 0, K = 1 is a command to reset the flip-flop; and the combination J = K = 1 is a command to toggle the flip-flop, i.e., change its output to the logical complement of its current value. Setting J = K = 0 does NOT result in a D flip-flop, but rather, will hold the current state. To synthesize a D flip-flop, simply set K equal to the complement of J. The JK flip-flop is therefore a universal flip-flop, because it can be configured to work as an SR flip-flop, a D flip-flop or a T flip-flop. NOTE: The flip flop is positive edge triggered (Clock Pulse) as seen in the timing diagram.even in the picture they Put SR/RS embeded, that mens JK can work like SR too. I will use this diagram to draw ripple counter. You may note similarity in input output combination too...RS table* We can summarize the operation of the RS-flipflop by the following truth table.R S Q Q' Comment 0 0 Q Q' Hold state 0 1 1 0 Set 1 0 0 1 Reset 1 1 ? ? AvoidJktableand the corresponding truth table is: J KQnext Comment 0 0 hold state 0 1 reset 1 0 set 1 1 toggleDoes that mean we use below coutner 'using 4 bit ripple counter using JK flip flops' as 4 bit ripple counter for RS flip flop too? at the max output states would differ only when both SR/JK is 1 1 ?Figure 1. A Simple Ripple Counter Consisting of J-K Flip-flopsMethod1: You will find answer here: http://www2.cs.uh.edu/~jhuang/JCH/LD/chap07.htmlHere you see how to create ripple counter using RS flip flop. Method 2: create a Toggle function in RS flip flop, then use it in place of typical jk flip flop ripple couters.
