Q. A system has poles at 0.01 Hz, 1 Hz and 80Hz, zeroes at 5Hz, 100Hz and 200Hz. The approximate phase of the system response at 20 Hz is :

(A) -90°
(B) 0°
(C) 90°
(D) -180°

💬 Discuss

✅ Correct Answer: (A) -90°

Explanation: pole at 0.01 hz gives -180° phase. zero at 5hz gives 90° phase therefore at 20hz -90° phase shift is provided.
