Digital circuit for the generation of colored noise exploiting single bit pseudo random sequence

Abstract

The generation of complex signal sources is important for test and validation of electronic systems. With reference to noise sources, commercial systems only provide white noise sources while the scientific literature only recently proposed circuits that generate programmable colored noise. This paper proposes a programmable colored noise generator that, while generating noise signals with features matching the state of the art, overcomes the previously proposed circuits in terms of speed (+10%) and logic resource occupation (-75%)
