    %% Frequency Response of an LC Resonator
% This example creates a series LC resonator and examines its frequency
% response. It first creates the circuit object and then uses the analyze
% method to calculate its frequency response. Finally, it plots the
% results - first, the magnitude in decibels (dB):

h = rfckt.seriesrlc('L',4.7e-5,'C',2.2e-10);
analyze(h,logspace(4,8,1000));
plot(h,'s21','dB')
ax = gca;
ax.XScale = 'log';

% The example then plots the phase, in degrees:

plot(h,'s21','angle')
