simplify the boolean expression: A' B' C' D' + A C' D' + B' C D' + A' B C D + B C' D

n variables can be combined to form .......... minterms

with integrated circuits it's the count of gates that determines the cost

uses only one full adder and a storage device to hold the generated output carry

The parallel method uses .. full adder circuits

The above image represents a .. bit full adder circuit

the signal must propagate through the gates before the correct output sum is available in the output terminals

total propagation time = propagation delay times and number of gate levels in the circuit

A decimal adder requires a mnimum of .. inputs and .. outputs since .. bits are required to code each decimal digit

We obtain a non-valid BCD representation when the binary number is greater than ...

The circuit for comparing two n-bit numbers has ... entries in the truth table

Decoders can have less than n^2 outputs

the name decoder is also used in conjunction with some code converters, such as a seven-segment-to-BCD decoder

.... is a combinational circuit that converts binary information from n input lines to a maximum of n^2 unique output lines

an example of encoder is

a combinational circuit that selects binary information from one of many input lines and directs it to a single output line
