Reference request in Circuit and Signals for Computational Neuroscience
Signals and System by Oppenheim (and others) was developed while he was teaching 6.003 at MIT. Similarly Foundations of Analog and Digital Electronic Circuits by Agarwal (and others) was developed while he was teaching 6.002 at MIT. Circuits, Signals and Systems by Siebert was written while he was teaching at MIT. Siebert was before my time, but I believe 6.002 and 6.003 where separate even when he was teaching and that despite the name, there is not much circuits in the book. I would suggest the Oppenheim book over the Siebert book, purely because it is newer, but unless you have an EE background, there are probably better references.
