Abstract:
1. A method of tracking a resolved signal, the method comprising: determining a first value representative of an energy of the signal at a first instant before a presumed occurrence of a local optimum of the energy of the signal; determining a second value representative of the energy at a second instant after the presumed occurrence of the local optimum; calculating a first product of a first positive integer and the first value and calculating a second product of a second positive integer and the second value, with the first positive integer smaller than the second positive integer; generating a first logical value from a comparison between the first and the second products; calculating a third product from a third positive integer and the first value and calculating a fourth product from a fourth positive integer and the second value, with the third positive integer smaller than the fourth positive integer; generating a second logical value from a comparison between the third and the fourth products; and, generating a detector output signal from a difference between the first logical value and the second logical value.
