Learn the key concepts of Electronics for A/L Physics, explained simply
About A/L Physics: The A/L Physics syllabus is structured across two academic years, covering fundamental and advanced topics in mechanics, waves, electricity, and modern physics. Every topic on Idasara Academy is mapped directly to the NIE curriculum.
Sequential Logic Circuit
A circuit whose output depends on both current inputs and the past sequence of inputs (i.e., it has memory).
Unlike combinational logic, sequential circuits store state using feedback. The output is a function of present inputs and the internal state (history). Example: a digital counter that remembers the last count.
Flip‑Flop (Bistable Multivibrator)
A fundamental 1‑bit memory element that has two stable states (0 or 1) and changes state only on a clock edge or control signal.
Flip‑flops are edge‑triggered (unlike latches, which are level‑sensitive). They form the building blocks of registers, counters, and finite state machines. Example: a D flip‑flop stores a single data bit until the next clock edge.
