Question

Consider the impedance function Z(s)=3(s+2)(s+4)/(s+1)(s+3). Find the value of R1 after realizing by first Foster method. (a) 9/2 (b) 2/9 (c) 9 (d) 1/9 I have been asked this question during a job interview.

Answer 1

The correct option is (a) 9/2 For explanation I would say: The first Foster form can be realized by taking the partial fraction of Z (s). On solving, we get Z (s)=3+(9/2/(s+1))+(3/2/(s+3)). So the value of R1 is 9/2Ω.
