Hi all,

This system consists of an DAC, a processor, and a ADC. The flow graph
is like as follows:

input-digital-signal -> DAC -> filter(Continuous Time) -> ADC ->
output-digital-sigal



That's a weird way to do things. Is it an academic exercise?

Actually that's the issue I face every single time I want to model a continuous-time plant from the point of view of my digital controller. There's a pretty direct solution (see my direct reply).

I hadn't realized it was for a simulation only. It would be weird for a final physical realization. Did you see my having-slept-on-it reply this morning? I hope Lucy did.


This is the only response from you that I see in this thread.
