If the transfer function of the following network is—
V0(s) = 1 Vi(s) 2 + RCs
The value of load resistance RL is—
-
- R/4
- R/2
- R
- 2R
- R/4
Correct Option: C
The given network
The given transfer function
| = | ||
| Vi(s) | 2 + sCR |
From given network
or
| = | ||
| Vi(s) | R + RL + RRLCs |
On comparing equation (i) and (ii) we get
RL = 1 and R + RL = 2
or
R = 2 – RL = 2 – RL = 1
It means,
RL = R
Hence alternative (C) is the correct choice.
