Answer»

b. +1, 0, -1 respectively

The sgn(f) is a signum function that is defined in the frequency domain as sgn(f) = 1, f> 0

= 0, f = 0 = -1, f< 0

Mathematically, the sign function or signum function is an odd mathematical function which extracts the sign of a real number and is often represented as sgn
