Q1:

The phase angle curve of G(jω) H(jω) can be drawn

A by adding the phase angle curves of individual factors

B by subtracting the phase angle curves of individual factors

C by multiplying the phase angle curves of individual factors

D by dividing the phase angle curves of individual factors

ANS:A - by adding the phase angle curves of individual factors

When terms are multiplied, phase angles are added.
