Abstract : In the patent input data representative of a variable environment including both signals and noise is delayed by multiple equal delay increments to generate identical multiple versions in delayed form. A selected version of the input data is compared with each other version, including the delayed data, in multiple comparators. The outputs of all comparators are summed and the sum is sampled at a rate such that the samples are statistically independent. The samples are then summed and compared with a predetermined threshold to indicate the presence or absence of signal in the input data.
