Question

In root locus technique, angle between adjacent asymptote is (a) 180°/(m+ n) (b) 360°/(m + n) (c) 360°/(m-n) (d) 180°/(m-n)

Answer 1

Option (d)

Step-by-step explanation:

In the root locus, method, the angle of asymptote or the angle between adjacent asymptote is calculated by using the given formula:

Angle of asymptote,
`\angle A = (180^(\circ)(2p + 1))/(m - n)`

If p = 0 (say)

then the above eqn becomes:

`\angle A = (180^(\circ)))/(m - n)`

where

m = no. of poles

n = no. of zeroes
