Bus signals – parallel signals transitioning from one level to other: Conditional change of on signal depending on another signal transition: Transition on a signal causes state changes in a BUS: More than one transition causes changes in a BUS: Sequential transition – one signal transition causes another signal transition and second signal transition causes third signal transition. These diagrams are frequently used as a tool to describe digital interfaces. Digital stimulus generators import, export, and translate digital waveform stimulus to drive simulators and test equipment. In the 3-bit ripple counter, three flip-flops are used in the circuit. Mind you, timing diagrams attempt to do this, sometimes very well, sometimes not so very well.
