ABSTRACT:
A system including method and apparatus for determining the energy content in a signal to be analyzed employs, in an apparatus aspect thereof, a sampling element for producing samples of the electrical signal to be analyzed, a local correlator for producing a plurality of signals corresponding to the samples delayed and multiplicatively combined with their complex conjugates, a bank of delay and adder systems for correlating the outputs of the multipliers in accordance with a binomial kernel, and a Fourier transformer for producing the distribution as a function of time and frequency. Local correlation is effected using a multi-element delay system, such as a shift register. Binomial correlation in the delay and adder systems is achieved by combining additively given samples with samples which are in other states of delay. Moreover, the banks have respectively different numbers of such delay and adder systems. The resulting analytic signal corresponds to a binomial kernel.
