ITPEC FE Morning October 2023 Question 20
ITPEC FE Morning October 2023 — Question 20 of 80
Flip-flop — a sequential circuit with two stable states used as a 1-bit memory element.
Why it's the answer:
- A flip-flop is a sequential circuit (has memory/feedback)
- It maintains exactly two stable states (0 and 1)
- Used as the basic building block of registers, counters, and memory
Why not others:
- (a) Adder circuit — combinational circuit; computes sums, stores nothing
- (b) Capacitor — an electronic component, not a logic circuit
- (d) NAND gate — combinational gate; no memory or feedback
Key rule: "Sequential circuit + two stable states" = flip-flop.
