RC impedance or RL admittance



PROPERTIES OF RC IMPEDANCE OR RL ADMITTANCE

1)Poles and zeros are alternating

2) Poles and zeros are simple and lie on the negative real axis of the s-plane.

3)The critical frequency nearest to origin is a pole which indicates a capacitor for RC impedance

4) The critical frequency farthest from  origin is a zero which indicates a capacitor for RC impedance

5)The residues of Z(s) at its poles are all positive and real

6) The slope of ZRC(σ) is negative and the slope of ZRC(-σ) is positive
7) ZRC(0) ≥ZRC(∞)

Methods for realising a RC IMPEDANCE OR RL ADMITTANCE function

1) Foster form 1

2) Foster form 2

3) Cauer form 1

4) Cauer form 2

FOSTER FORM 1
It is used to realize impedance function. 


 FOSTER FORM 2
It is used to realize admittance function.
 3) CAUER FORM 1
4) CAUER FORM 2
