Q1:

In a minimum function

A the degree of numerator and denominator are equal

B the degree of numerator and denominator are unequal

C the degree of numerator is one more than degree of denominator

D the degree of numerator is one less than degree of denominator

ANS:A - the degree of numerator and denominator are equal

If degrees of numerator and denominator were unequal, a pole or zero can be removed. Such a function cannot be a minimum function. Therefore degrees of numerator and denominator must be equal.
