| Another much more simple way to achieve similar work and results is to generate a pseudo-random signal having a spectrum mask representative of all impairment signals. This can be achieved in digital domain by appropriate FIR filtering of some white Gaussian noise. | Another much more simple way to achieve similar work and results is to generate a pseudo-random signal having a spectrum mask representative of all impairment signals.
