Seems accurate.
What specific circuit are you questioning?
I was trying to make a low pass filter, that can average out a Pulse Density Modulation signal... to make a crude digital to analogue converter. I wanted to prototype it in software before I bought the components I need.
You can buy loads of types of A/D converters with all the antialiasing filters etc you could ever want. The IC section of the maplin catalouge alone has loads of them :-D
