Question

Which two networks can be used for impedance matching?

(a) pi network and T network

(b) pi network and bridge network

(c) bridge network and T network

(d) pi network and omega network

I have been asked this question in class test.

My enquiry is from Instantaneous Frequency and Frequency Modulation topic in division Angle Modulation of Analog Communications

Answer 1

Right option is (a) pi network and T network

For explanation I would say: If a source with low impedance is connected with a load with high impedance then the power that can pass through the connection is limited by higher impedance. Generally the two networks, pi and T are used for impedance matching.
