**Directions:** It consists of two statements, one labelled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answers to these items using the codes given below:

**Statement (I):**

The polar plot has limitation for portraying the frequency response of a system.

**Statement (II):**

The calculation of frequency response is tedious and does not indicate the effect of the individual poles and zeros.

**Polar plot:**

- The Polar plot is a plot, which can be drawn between the magnitude and the phase angle of G(jω)H(jω) by varying ω from zero to ∞.
**The calculation of frequency response is tedious, and it does not indicate the impact of individual components of open-loop transfer function**.- Another disadvantage of this plot is that it cannot tell how many poles are in right side of the complex plane.
- To overcome this disadvantage, magnitude is plotted by varying frequency from that is known as the Nyquist plot.
**It has no limitation in portraying the frequency response of a system**.

Therefore, Statement (I) is false but Statement (II) is true.
