A signal processor is for receiving an input signal y. The input signal y has in it a signal x and has a conditional density function, given that the signal x is present, p(y¦x). The signal processor includes a memory for storing the amplitude-density-function of the signal x, p(x). The memory is coupled to the processor input so that the memory is addressed by the input signal y. An amplitude-density-function generator is coupled to the processor input and to the memory generates the product of the conditional density function p(y¦x) and the density function p(x). The processor of the invention also includes apparatus for detecting the peak of that product.
