spectrum()

Returns the spectrum as a complex array

Syntax
spectrum(function(0), NumPoints, Period, Delay, Window)

Name	Description	Range	Type	Default	Required
function(0)	Function with a single argument		function		yes
NumPoints	Number of points	[0, ∞)	integer, real		yes
Period	Time step period	[0, ∞)	integer, real		yes
Delay	Delay	[0, ∞)	integer, real	0	no
Window	Specifies if windowing is to be applied	[0, 1]	integer, real	0	no

Creates a spectrum:

fCos\(x\) = cos_pulse\(x, 0, 2, 0, 100ps, 100ps, 200ps, 400ps\)

specV = spectrum\(fCos\(time\), 128, 400ps\)
