What term refers to the pulse generator used to synchronize switching circuits?

• A. NAND Logic Gate
• B. Truth Table
• C. Clock Pulse
• D. Flip-flop

Answer: (C)

Clock pulse is the timing signal used to synchronize switching circuits. In digital systems, you need a regular timing reference so all parts change state together. The clock pulse provides periodic edges that trigger changes in sequential devices like flip-flops and counters, keeping every part in step and avoiding timing mismatches. It’s typically produced by an oscillator and is a stable square wave with a defined frequency and duty cycle. The other options don’t serve as the synchronization signal: a NAND logic gate is a basic functionally unrelated gate, a truth table describes input-output behavior rather than generating timing, and a flip-flop is a storage element that changes state in response to a clock edge rather than acting as the timing signal itself.
