<p>A circuit (2,170,200,300) for generating a digital noise signal characterized by an evenly distributed frequency content for a particular frequency bandwidth of the digital noise signal includes a word signal generator (4,101) for generating a random sequence of N-bit digital word signals with each cycle of a system clock signal provided to the word signal generator, where N is a non-zero integer. The noise generating circuit further includes a shaping circuit (6,114) which transforms the random sequence into a shaped sequence of N-bit digital word signals, and a frequency synthesizer (12) which is responsive to the shaped sequence and which generates the digital noise signal. <IMAGE></p> |
