Solution:
For proper impedance matching, The source voltage should be applied to the load with out attenuation.
The following are the conditions for impedance matching circuit.
condition 1: Z2 >> Z1,
so that V2 = V1.
condition 2: Z3 << Z4,
so that V4 = V1.
SO attenuation by voltage divider circuit is negligible and total input voltage is applied to the load at Z4.
