  1. If the transfer function of the following network is—
    V0(s)
    =
    1
    Vi(s)2 + RCs

    The value of load resistance RL is—


    1. R/4
    2. R/2
    3. R
    4. 2R
Correct Option: C

The given network

The given transfer function

VOs
=
1
Vi(s)2 + sCR
…(i)
From given network

or
VOs
=
RL
Vi(s)R + RL + RRLCs
…(ii)
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.
