In the area of computational neuroscience, there are basic theories from electric circuits and signal processing to be applied. For background study, which reference will be more suitable ?
Personally, I don't have any background knowledge in circuit, or signals.
(Cited by Dayan's book in Theoretical Neuroscience)
"Circuits, Signals and Systems" , William M. Siebert
This book seems contains both electric circuits and signal processing, but maybe not from the ground.
Or combination or following two books
"Signals and System", Oppenheim
"Foundations of Analog and Digital Electronic Circuits", Agarwal
These two are much heavier than Siebert's, they are good ones, but is it necessary to thoroughly read these two complete detailed books for computational neuroscience ?
