Question 20

these are fundamental components of digital systems that manipulate binary signals (0s and 1s) using logical operations

Answer 20

switching circuits

Question 21

a fundamental type of digital logic circuit in which the output depends only on the current input values and doesn’t rely on any past input values or the circuit’s internal state

Answer 21

combinational circuits

Question 22

These circuits perform specific functions or operations based on the input data, using logical gates to generate the output

Answer 22

combinational circuits

Question 23

another fundamental type of digital logic circuit, distinct from combinational circuits
