#1
Front (Question)

What are the 2 outputs of a half-adder.

Back (Answer)

-Sum bit (xor gate) -Carry bit(and gate)

#2
Front (Question)

What are the 2 outputs of a full-adder.

Back (Answer)

-Sum bit (xor gate) -Carry bit(or gate)

#3
Front (Question)

What are flip-flops?

Back (Answer)

-They are circuits/ electronic components. -With two states -USed for data storage … to store one bit of data.

#4
Front (Question)

Difference between SR and JK flip-flop.

Back (Answer)

-SR flip-flop has undefined / invalid / indeterminate state // JK flip-flop is stable -JK flip flop has a clock pulse

#5
Front (Question)

SR flip-flop. What are the two inputs and what gates is it constructed with.

Back (Answer)

-Inputs are R/Reset and S/set. -Can be constructed using two NAND gates or two NOR gates.

#6
Front (Question)

Purpose of an SR FlipFlop

Back (Answer)

-Use to store a binary digit.

#7
Front (Question)

Why is the JK flip-flop an improvement to the SR flip-flop?

Back (Answer)

-The SR flip-flop has an invalid combination of SR which allows Q and notQ to have the same value. -The JK flip-flop does not allow Q and notQ to have the same value.

#8
Front (Question)

Advantages of JK flip-flop

Back (Answer)

-All four possibilities are valid. -The 1-1 combination changes output to logical complement. -Unstable state avoided. -Invalid state cannot occur.
