TL;DR: A counter is a sequential circuit that steps through a fixed binary sequence on each clock edge. A finite state machine (FSM) generalizes this with conditional transitions driven by...
TL;DR: The JK flip-flop is the most versatile 1-bit memory element. Its J and K inputs at the active clock edge select one of four modes — hold (00), reset...
TL;DR: A Johnson counter is a synchronous shift register where the inverted output of the last stage feeds back to the first stage. With flip-flops it produces unique states, and...
TL;DR: A T flip-flop toggles its stored bit on every active clock edge when T=1 and holds it when T=0. Its characteristic equation is . Tied permanently to T=1, it...
