Figure
4.2-18 Frequency response of L-C series resonator circuit
As is to be expected, maximum power transfer between source and load is achieved at the resonant
frequency (Figure 4.2-18).
Video 4.1 illustrates the concepts explained in section 4.2.1, 4.2.2 and 4.2.3 by means of
Microwave Office simulations.
