He found that the basilar membrance acts as a shift invariant linear system (by testing shift-invariance, the scalar rule, and superposition). He then used sinusoidal stimuli (pure tones) to measure the frequency response at different points along the basilar membrane. He then was able (using linear systems theory) to predict the response (that is, the motion of the basilar membrane) for any sound.
for real ..u can go to my v block..http://www.cns.nyu.edu/~david/courses/perception/lecturenotes/pitch/pitch.html
with a great plesure ..please try it..
