The
elementary particles of the atom's nucleus, are being held together by the
strong nuclear force. The potential of this force, as function of the distance
between the particles, is derived by the given formula. exponential curve (a=0)
Adding
a large number of such filters spaced across the audible frequency range, the roundedexponential curve or roex
curve, is formed (Patterson and Moore, 1986). This curve is slightly
asymmetric, being wider on the lowfrequency side.
The reciprocal of the Hoerl curve is found as the vapor pressure curve.
1) y = (1+x) e^{x} is equivalent to y = x e^{x} + e^{x}.
