I hope this is the right forum for this type of question.
There is a device which is a kind of band-pass filter used with various musical instruments (analog) which I would like to copy. Just building an identical circuit is not good enough since the different components in the circuit have unique imperfections which contribute to the overall response of the device. Myself and other have built many prototypes and invested a lot of work but so far the results are not good enough. Since I am not much of an analog guy I thought to go for a more "brute force" approach - replicate the response of the entire device (looked at as a black box). The question is how to start, what is the method I should use?
I think the general idea is to see freq. and gain response to various input signals, come up with some formulas and / or graphs that describe various behaviors and replicate that using a DSP. This must be very methodic so I would appreciate any insight to the work process as required. I have access to scopes and a signal analyzer.
