Abstract:
1. A method for sampling an analog input signal and storing digital presentation said samples in a memory, said method comprising: generating a sequence of clock pulses at a predetermined frequency F generating a pseudo-random integer A ranged from K to K+N where K and N are predetermined constants equal to one or greater than one, at every sampling pulse; dividing said sequence of clock pulses by said integer A to select one last pulse from every series of A clock pulses; forming a sequence of sampling pulses from said sequence of selected clock pulses by means of the following steps: (a) generating a pseudo-random integer B ranged from zero to M, where M are predetermined constants equal to one or greater than one, in parallel with said integer A; (b) delaying the selected clock pulse by value D×B, where D is equal to 1/F sampling an analog input signal at said delayed clock pulse, and converting the said sample value to a predetermined digital format; and storing the current signal sample value in a memory.
