Define a flip-flop in digital electronics.

• A flip-flop is a bistable device that stores one bit of data.

• A flip-flop is a single stable device that stores two bits of data.

• A flip-flop is a device that only allows data to flow in one direction.

• A flip-flop is a type of analog circuit used for amplifying signals.

What are the two stable states of a flip-flop called?

• 0 and 1

• On and Off

• A and B

• True and False

What is the purpose of a multiplexer in digital circuits?

• To amplify a single input signal for better clarity.

• To convert analog signals into digital format.

• To select and route one of multiple input signals to a single output.

• To store multiple input signals for later use.

Describe the operation of a SR latch.

• An SR latch is a device that only allows high signals to pass through.

• An SR latch is a type of microcontroller used for processing data.

• An SR latch is a memory device that holds a binary state based on Set and Reset inputs.

• An SR latch is used to amplify signals in a circuit.

What is the significance of propagation delay in digital circuits?

• Propagation delay determines the power consumption of a circuit.

• Propagation delay is irrelevant in high-speed digital circuits.

• Propagation delay only affects analog circuits.

• Propagation delay is significant as it impacts the speed and timing of digital circuits.

What is the main advantage of using digital circuits over analog circuits?

• Lower power consumption than analog circuits.
