From the figure, it can be observed that the output Q0 of the first flip flop is applied as a clock pulse to the second flip flop. The symbol for the clock pulse indicates a negative triggered clock pulse. JK inputs of flip flops are supplied with high voltage signal maintaining them at a state 1. Here two JK flip flops J0K0 and J1K1 are used. The circuit arrangement of a binary ripple counter is as shown in the figure below. While choosing the type of flip-flop it should be remembered that Ripple counters can be designed only using those flip-flops which have a condition for toggling like in JK and T flip flops. As here n value is 2 we use 2 flip-flops. Let us look at the working of a 2-bit binary ripple counter to understand the concept.Ī binary counter can count up to 2-bit values. Based on the number of flip flops used there are 2-bit, 3-bit, 4-bit…. The working of the ripple counter can be best understood with the help of an example.
