of the type of transmission system we have been studying. It does seem, nevertheless, that our new estimates of critical bandwidth are perhaps a bit too narrow, just as our estimates of noise bandwidth from intensity discrimination are not quite wide enough.
All things considered, the indications of progress are obvious. We have been able to characterize an active detection network based upon the principle of stochastic multiplication. We have managed to do so without getting hopelessly lost in the myriad complexities of the auditory pathways. Abandoning total dependence on the stimulus, and constructing the functional outline of an amplifier network (a hybrid of stimulus, receptor, and transmission mechanisms) generates solutions for a variety of problems deemed either intractable or overwhelmingly complex when approached in the conventional stimulus-oriented way. Time will tell whether this system is the one we have been seeking.
