A menu at lower right offers a choice of functions f(u) of period 2π .
A slider or [<], [>] keys select the value of the circular frequency ω.
The graphing window at left displays graphs of f(ω t) (in cyan)
and of the steady state response of the harmonic oscillator with natural
frequency 1 to this input signal (in yellow). Rolling the cursor over the
graphing window produces crosshairs and a readout of the values of t and x.
Above
the ω slider the graph of the root mean square magnitude of the
system response is plotted as a function of ω. The currently chosen
value of ω is indicated by a yellow line segment.
Roll
the cursor over the RMS window to produce a readout of the value of
the root mean square magnitude of the system response, and a horizontal yellow
line relating that value to the graphing window.
