I have to add noise to my circuit analysis. Since, Pspice do not have the noise source, I have used "VPWL_F_RE_FOREVER".
In this i have given a input data file containg the data of gaussian white noise generated using matlab. Now the problem is,
I have a data with equally spaced step size. say for example 1ms. I set "Start saving data=0, TSTOP=20m,maximum step size=1m" .
While the simulation, the psice takes nonuniform step size for the simulation. In this situation, suppose if i have the noise data for 0m, 1m,2m and so on... Between the two succesive time step the pspice generates few new steps as its own. But I strictly need the simulation with the time step used in the input data file.
Can any one please help me in this regard?
In reply to oldmouldy:
I accept your point. But one thing is not clear for me. Since we have to study the effect of noise on a particular circuit, we should have to add a noise data to each iteration. Right? If so then how to do it in orcad?
