- Abstract:
- Noise signals are needed for test and validation of electronic systems and communication channels. Available noise sources are however limited to wide band white noise sources while the arbitrary waveform generators are poorly suited for the generation of long random or pseudo random noise sequences. The paper explores the possibility of using a single bit pseudo random sequence, filtered with a FIR filter, for the generation of an analogue noise signal with programmable spectral features. The results show that the technique is suitable for real time applications. When implemented on a Field Programmable Gate Array device, the technique uses less resources compared with the state of the art.
