Abstract:
A method for generating spread spectrum modulated signals, comprising:receiving a number input samples representing a digital signal as successive bits at a specified rate; grouping the successive bits into at least a first sub-group of bits and a second sub-group of bits, alternately applying a selected one of the first sub-group of bits and the second sub-group of bits to a first set of address lines of a storage device that stores values corresponding to filter responses of the digital signal, wherein the storage device is addressable by a combination of the first set of address lines and a second set of different address lines for accessing a selected one of the stored values; and modifying a bit pattern applied to the second set of address lines, depending on whether the first sub-group of bits or the second sub-group of bits are applied to the first set of address lines.
