MicrocontrollerRelated: The clock sets the pace for instruction execution and peripheral timing.
Digital signalRelated: Clock edges define when many digital systems sample or update signal values.
Digital logicRelated: Clock edges synchronize when sequential circuits update their stored state.
Digital circuitRelated: Clock edges synchronize when sequential circuits update their state.
NOT gateRelated: Inverters can buffer or invert clock signals as they travel through a circuit.
Electronic oscillatorRelated: Clock generators distribute oscillator timing to processors and logic.
Music sequencerRelated: Clock pulses keep sequencers and connected instruments playing in sync.
Synchronous circuitRelated: Its transitions define when synchronous state elements may update.
