It is useful for the construction of binary counters, frequency dividers, and general binary addition
devices. The T flip flop can be implemented from a special JK flip flop. The special JK flip flop is the
one where the inputs J and K are tied together. This type of flip flop operates by toggling the previous
state every time a clock pulse is applied at the input T. T = J & K.

Activity

1 Use a JK flip flop implemented on AND and NOR gates and from it show how you would implement
a T flip flop

2 Produce its truth to show how the produced T flip flop operates differently from the original JK flip
flop

3 The truth table of the produced T flip flops has how many possible input combinations?
