i have a piecewise like " g "

g := piecewise(0 <= t and t <= 0.2e-1, 122.63, 0.2e-1 < t and t < .287, 0, .287 <= t and t <= .307, 122.63, .307 < t and t < .335, 0); plot(g, t = 0 .. .335)

this function is semi periodic just for 10 times consecutive . i want to define it

example     k=[g g g g g g g g g g  g ] or somthing like that.

i want to plot fft form of final piecewise function

and then filter it . and plot them.
