hello,

I need to do an electronic experiment in our physics lab.
My idea was to create a wave with RLC circuit, whice represents a function that can be describe using a fourier series.

for example: the function f(x) = -pi/2 ( where -pi < x < 0) and pi/2 (0 < x < pi), can be describe using the fourier series (series of cos and sin functions):
f(x) = 2(sin(x) + sin(3x)/3 + sin(5x)/5 + ...)

I want to design RLC circuit that will show me this function on the scope.
I believe I know how to design the function for getting the right frequencies,
(By combining the components in parralel, so the branches' self-frequencies will be joined)

but I do not know how to addjust the components so the ammplitude will fit.
(in the example, the applitude for sin(x) is 2, for sin(3x) is 2/3 and so on...)

Could you help me with this issue?

Thanks, Maor
