Hi,

I'm using DTV-lib (2003C.300). I need a flicker noise generator.

I have tried NoiseFMask but when looking at

the noise with SpectrumAnalyser the noise is

falling 20 dB/dec not 10 dB/dec as I specify in NoiseFMask. I cannot use a IID_Gaussian and put a filter after since this whould also give 20 dB/dec.

Any tricks???

Kindly, CG

If I use NTones with phase noise, what's the Ntones' carrier frequency to set? Shall I set it to zero Hz?

Can you be a little more specific for the two problems you encountered when trying to pass white noise through a filter?

What is the divide by 0 problem you mentioned? Is some model trying to do a division by 0 and the simulation terminates?

What is the convergence problem you mentioned? Are you doing cosimulation?

Unfortunately, I am not knowledgable enough to answer circuit envelope convergence or noise questions.

You might want to post the question on the "Analog Simulation" forum area.
