Abstract:
Starting with the assumption that the output of a biological transducer is the linear sum of discrete waveshapes, then under appropriate conditions, such a system may be modelled by a transfer function whose input is a train of delta functions. The transfer function is obtained by averaging over the population of possible waveshapes. The representation of the input as a train of delta functions facilitates the calculation of its frequency power spectrum. A number of examples of possible physiological interest are given.
