Question:

Digital representation of analog signal across resistor?

If I have discrete data from a A/D converter, is there an algorithm or transfer function to apply to the digital data to simulate going through a simple analog resistor? or any other type of basic component for example?

i'm interested in learning how to digitally simulate an analog circuit.

  1. Sure!

    It's called Ohm's Law, E = I R or voltage = current times resistance.

    The A/D converter merely measures the voltage at a given point at a given time. All components have transfer functions, google things like "capacitor" and "inductor" to get the governing equations.

    Edit: Transfer functions used in control theory are not the same as regular circuit analysis. Get a control theory book, first part will be how to model systems. Just do the arithmetic they specify and off you go. It's fairly straightforward; you can probably find routines online to do the Laplace transforms.
