Hello, I would like to know about methods of modeling bandlimited noise. Indeed by noise here I mean is simply a class of signals with a given frequency range. It is not as specific as noise in a class of electronic circuits. Moreover, a model I would like to have is in time-domain. Indeed, I am doing research in validation of analog circuits basically defined as a differential algebraic system. When wishing to prove that the circuit can work under ANY input signal with a given frequency range, one could regard the input signal as "noise". I am wondering if any of you could give some pointers to existing literature. Many thanks in advance.
