A noise source that produces white noise is essentially an inexpensive broadband signal generator with an extremely flat (constant) power density output versus frequency. Noise sources are almost insensitive to temperature and supply voltage variations. Noise sources are therefore used for Built-in Testing (BIT), Fault Isolation Testing (FIT), and calibration in communication and radar warning systems to ensure the reliability and performance of the link. The webinar will be about the discussion of noise relevant parameters and applications.
