DE Fall Final Practice

Front

What is the output of an AND gate if the inputs are 1 and 0?

Back

0

Front

What is the Boolean expression for the truth table shown: D = B(A'C + AC')?

Back

D = B(A'C + AC')

Front

What is voltage?

Back

The energy given to electrons.

Front

True or False: Flip flops are edge triggered and latches are level triggered.

Back

True

Front

Express 1500 Volts in SI notation.

Back

1.5 kV

Front

What is the output of an OR gate if the inputs are 0 and 1?

Back

1

Front

Define a flip flop in digital electronics.

Back

A flip flop is a circuit that has two stable states and can be used to store binary data.

Front

What is the primary function of a latch?

Back

To hold a binary state until it is changed by an input signal.

Front

What does the term 'edge triggered' mean in the context of flip flops?

Back

It means the flip flop changes state only at the moment of a clock signal transition.

Front

What is the difference between AC and DC voltage?

Back

AC voltage alternates direction, while DC voltage flows in one direction.
