Transfer function and bode plot

This demo illustrates the effect of a dynamic system described by a transfer function on a sine input.
You can select the amplitude and angular frequency using the sliders below and see the amplification and phase shift highlighted in the bode plot. The output shows the input-sine in blue, the output in black.
