The logical expressions are

(X NOR Y ) OR Z ⇒ $(\bar X \bar + \bar Y) + Z$
(A NAND B) AND NOT C ⇒ $(\bar A \bar \cdot\bar B) \cdot \bar C$

<h3>How to determine the logical expressions?</h3>

<u>Logical expression 1</u>

X and Y are linked by the NOR gate.

So, we have:

X NOR Y

The X NOR Y is linked to Z by the OR gate.

So, we have:

(X NOR Y) OR Z

Hence, the logical expression is (X NOR Y ) OR Z ⇒ $(\bar X \bar + \bar Y) + Z$

<u>Logical expression 2</u>

A and B are linked by the NAND gate.

So, we have:

A NAND B

The A NAND B is linked to C by the AND gate.

So, we have:

(A NAND B) AND C

Hence, the logical expression is (A NAND B) AND NOT C ⇒ $(\bar A \bar \cdot\bar B) \cdot \bar C$

What are some programs that you have used that have condition-controlled loops and count-controlled loops?

gladu [14]

Some programs that we have used that have condition-controlled loops and count-controlled loops due to the following reasons.

Explanation:

Condition-controlled loops

A program could be made more intelligent by programming it to avoid hazards. For example, if the robot vehicle is 3 cm from the edge of the table and you tell it to move forwards 5 cm, it will drive off the edge of the table. To stop this from happening, you might write a condition-controlled loop like this:

move forward

repeat until (touching table edge)

Condition-controlled loops can be used to add a high degree of intelligence to a computer system.

Count Controlled Loops

A count controlled loop is a repetition structure that iterates a specific number of times

You can write a count controlled loop using a

while() loop.

For example:

counter = 0

while counter < 5:

print (“This will print 5

times”)

counter += 1
