Claim Text:
1. A method of frequency discrimination associated with a Doppler effect, comprising: mapping a first frequency of a first audio signal to a first set of frequency bins of a plurality of frequency bins, each frequency bin of the plurality of frequency bins corresponding to a different frequency, and the first audio signal emitted from a moving object at a first time; mapping a second frequency of a second audio signal to a second set of the plurality of frequency bins, the second audio signal emitted from the moving object at a second time; firing a first plurality of neurons based at least in part on the first frequency mapped to the first set of frequency bins, each one of the first plurality of neurons corresponding to a frequency bin of the first set of frequency bins; firing a second plurality of neurons based at least in part on the second frequency mapped to the second set of frequency bins, each one of the second plurality of neurons corresponding to a frequency bin of the second set of frequency bins, the first plurality of neurons and the second plurality of neurons corresponding to a first layer of neurons of a network, and the firing of the first plurality of neurons and the second plurality of neurons based at least in part on a relative speed of the moving object towards or away from a receiver of the first audio signal and the second audio signal; and estimating the relative speed of the moving object based on a firing pattern of the first plurality of neurons and the second plurality of neurons and a time difference between firing the first plurality of neurons and the second plurality of neurons.
