Bessel Functions of Integer Order

 This applet graphs Bessel functions of order 0..4, over the range 0 < x < 20.0

Bessel functions can be used to calculate the frequency spectrum of a simple FM synthesis pair. The amplitude of the nth sideband is Jn(I) where I is the index of modulation (mod_amp/mod_freq). Note that when the modulation amplitude is 0, I=0, and so, the center frequency (corresponding to J0) is the only sideband in the spectrum.
Methods in the class com.softsynth.jmsl.util.Bessel allow the user to calculate Bessel functions of integer order.
