QUESTION: 1

In a double tuned circuit, consisting of two magnetically coupled, identical high Q tuned circuits, at the resonance frequency of either circuit, the amplitude response has

Solution:

Since quaiity factor and Q is high therefore, the resonant frequency ω_{0} will be high. Hence, the amplitude response will have a peak always

QUESTION: 2

A network function contains only poles whose real-parts are zero or negative. The network is

Solution:

Poles are at can be zero or negative). The system will be stable if the poles at jω-axis are simple.
