. The corner frequencies are—G(s) = 1 + s s(1 + 0·5s)
-
- 0 and 1
- 0 and 2
- 0 and –1
- 1 and 2
- 0 and 1
Correct Option: D
For the given system
| G(s) = | |
| s (1 + 0.5s) |
in order to calculate corner frequency compare given equation with general equation.
| G(s) = | |
| s (1 + sT2) |
| T1 = 1, corner frequency ω1 = | = | = 1 | ||
| T2 | 1 |
| T2 = 0.5, corner frequency ω2 = | = | = 2 | ||
| T2 | 0.5 |
