Waveforms & Timers
A waveform with equal high and low times
What is a square wave?
The gate that outputs HIGH only when all inputs are HIGH.
What is an AND gate?
This multivibrator has one stable and one quasi-stable state.
What is a monostable
multivibrator?
Basic memory element in digital electronics.
What is a flip-flop?
Circuit used to convert sine wave to square wave.
What is a Schmitt trigger?
The IC commonly used for generating time delays and oscillations.
What is the 555 timer?
A universal logic gate.
What is a NAND gate?
This multivibrator switches continuously between two quasi-stable states.
What is an astable multivibrator?
A flip-flop that toggles its state on every clock pulse.
What is a T flip-flop?
Digital circuit used to count pulses.
What is a counter?
The time duration for one complete waveform cycle.

The gate that performs logical inversion.
What is a NOT gate?
A bistable circuit with two stable states.
What is a flip-flop?
A flip-flop with Set and Reset inputs.
What is an SR flip-flop?
Used for generating clock signals in digital circuits.
