Mathematics
1 answer:
horsena [70]3 years ago

Answer:

Division is not closed

explanation:

addition and subtraction are closed for polynomials because the result of adding and multiplying two polynomials is always another polynomial. Division on the other hand is not closed. If you divide two polynomials, the result is not always a polynomial.

Design a logic circuit to take input signals P, Q, and R and output a 1 if , and only if, P and Q have the same value and Q and
svet-max [94.6K]

Step-by-step explanation:

We have 3 given inputs namely P, Q, R and we have to draw a logic circuit which will give the output 1 if , and only if, P and Q have the same value and Q and R have opposite values.

So, first of all we make a truth table for this

P        Q        R        Output(Y)

0        0        0           0

0        0         1           1

0         1        0           0

0         1         1           0

1         0        0          0

1          0        1           0

1          1        0           1

1          1         1           0    

From the truth table we can see that the output, Y can be given by

Y=\bar{P}\bar{Q}R+PQ\bar{R}

So, the logic circuit for the given logic equation can be drawn as shown fig.
