Problem 1

A 50Ω Source has 2W maximum available power. Determine its Thevenin and Norton equivalent circuits.

Solution

Rsource=Rthevenin=50Ω as if we turned off source and see from output terminal we will find only it Pmax=Vthevenin24Rthevening=2W Vth=20V Inorton=VtheveninRthevenin=0.4A

Problem 2

If the source of Problem (1) is to be connected to a load of impedance 75j25Ω, design the required matching network. Hence, determine its Z, Y and ABCD parameters.

Solution

Z=[Z11Z12Z21Z22],Y=[Y11Y12Y21Y22],T=[ABCD] [V1V2]=[Z11Z12Z21Z22][I1I2] Z11=V1I1|I2=0=75j25 Z12=V2I1|I2=0=75j25 Z21=V1I2|I1=0=75j25 Z22=V2I2|I1=0=75j25
