Abstract

Pickupovi električne gitare mogu se analizirati kao skoro linearni promjenjivi izvor i RLC krug spojen na izlaz izvora. Taj RLC krug se ponaša kao niskopropusni filtar koji oblikuje signal koji izlazi iz pickupa. Prijenosna funkcija RLC kruga pickupa se može mjeriti i sweep generatorom, gdje oba pristupa daju približno jednake rezultate. U fazi sinteze želja je simulirati bilo koji pickup bilo kojim pickupom. To se pokušava postići propuštanjem signala jednog pickupa kroz njemu recipročan filtar te filtar koji oblikovan po drugom pickupu. Niti jedan od dostupnih izmjerenih pickupova nema stabilne recipročne filtre te se postavlja pitanje postoji li fizički izvediv pickup koji bi ga imao. Alternativa je konstrukcija sintesajzera s više oscilatora.

Abstract (english)

A guitar pickup can be analysed as a AC source connected to a RLC circuit. This RLC circuit is in fact a low pass filter which shapes the output signal of the pickup source. The transfer function of that RLC circuit can be calculated by measuring the R, L and C parameters; or, can be measured using a sweep generator. Both approaches give similar results. Synthesising a guitar pickup is done either by creating a multiple-oscillator synthesiser or by neutralising the transfer function (using a reciprocal transfer function) and filtering the signal through a transfer function of another pickup. None of the pickups measured have a stable, usable reciprocal transfer function. That leaves an open question - is it possible to wound a pickup which has a one?
