The 2-phase dual-rail protocol in the concept of asynchronous handshaking relies on detecting signal transitions.
How do we detect a signal transition from LOW to High or HIGH to LOW? What is the output of this detection? A permanent High? or LOW? or another transition?
I need the transistor level schematic or at least a few words on the design concept to help me come up with the design by myself.
My initial thought is to put a memory element on the signal and then after the transition happens we can compare the signal with previous value and detect a change, but then how do we detect the transition itself?
