| Description
|
This
module expects to receive spike probabilities as an input signal, which are
then converted to spike events using a random number generator. It uses the
geometric distribution method (see routine The GeomDist_Random(...) Routine) to
produce the results for s specified number of fibres (without the need for a
loop). A refractory effect is also applied (see module 0).
This approximation runs much faster then the other less efficient auditory
nerve modules, but only when a large number of fibres is specified. When a
smaller number of fibres is used, then the approximation starts to fail. If in
doubt, then always check the output using this module against the output using
the "ANSpikeGen_Simple" module.

Figure [53] Output for Binomial approximation spike generation test.
Comments:
This test program shows the Binomial spike generation routine used in conjunction with the Meddis '86 hair cell. It shows the stochastic response expected of a real AN fibre.
