NOTE: you can easily implement it by yourself … give it a shot

2 Lecture 12 Counters Instructor: Roman Chomko EE120A Logic Design, 10U Electrical Engineering University of California - Riverside T Flip-Flops (Toggle) Most frequently used in counters and frequency dividers however if possible should be avoided since this is an example of the asynchronous design . We’ll learn how to do it better in a few lectures from now. T flip-flops change state on every tick of the clock. Note that the signal on the flip-flop’s Q output has Precisely half the frequency of the T input. NOTE (again): you can easily implement it by yourself.
