    say you have built a circuit in which the objective was specified and carried out. How would you go about explaining the circuit?

    also how would you analyze the circuit? What results would you show?

    Kind Regards

    Hello Leeb:)
    I would give a different explanation to my mother, than I would give on this forum, so I think that a critical question is: "Who is your audience?"

    PS You could put the circuit up here for us to analyse and see if we can help more directly.

    Yeah sure, see the attached.

    If you cant make it out it goes from left to right as

    1) full-bridge circuit
    2) 3 op-amp instrumentation amplifier
    3) Phase sensitive detector switched by a CMOS 4066 and driven by a square wave from LM311 comparator

    This is for a university presentation.


    also its not finished yet so after the PSD will be a low pass filter then a howland current source.

    May we know the intended function the circuit satisfies?

    I would consider drawing a block diagram and explaining the various functional blocks and how they achieve the desired result before showing the contents of these functional blocks and explaining how each of them implements the function.

    It may be necessary to discuss the interaction between functional blocks if certain voltage levels or impedance matching is required.

    (And I've moved this to homework help where it seems to belong)
