Question

2. Resonant circuits are employed in electrical engineering for narrow and broad band frequency selective filtering. Impedance of R-L-C elements versus frequency is the understanding starting point, followed by R-L R-C and R-L-C circuits of various kinds.

a. Plot the impedances Z_L and Z_C versus frequency on:

1. A linear impedance scale

2. A log impedance scale and show the slope versus frequency is 20 db per decade of frequency
