AIn practice ~~particular~~a device may consist of circuitry that has one or the other or a mix of the two.<ref name="we">[[Wikipedia:Electronics]]</ref> == Getting started for SDIY ==▼ A linear circuit is one in which, for a [[Sine wave\|sinusoidal]] input voltage of [[frequency]] ''f'', any steady-state output of the circuit (the [[Electric current\|current]] through any component, or the [[voltage]] between any two points) is also sinusoidal with frequency ''f''. Note that the output need not be in [[phase]] with the input.<ref>''Linear circuit design handbook'' by Hank Zumbahlen, Newnes, 2008, ISBN 0-7506-8703-7</ref> In the 1950s and '60s experimenting with electronics was simpler but limited in what could be produced. These days it very much more sophisticated. However with the components and [[tools]] now available, a lot more can be achieved that back then would have taxed a huge research lab.<ref>''Build Your Own [[Printed Circuit Board]]'' by Al Williams, Tab, 2003, {{ISBN\|978-0-07-142783-8}}</ref> One of the traditional paths to learning electronics is amateur radio.<ref>Embedded, [http://www.embedded.com/electronics-blogs/break-points/4370279/Ham-radio-today Ham radio today] by Jack Ganssle, 2 Apr 2012</ref> First gain experience with some simpler [[audio electronics]] project(s), and build up the knowledge, skills and equipment.<ref>StackExchange EE, [http://electronics.stackexchange.com/questions/6077/building-a-synthesizer-with-no-prior-experience/6085#6085 Building a synthesizer with no prior experience]</ref> Developing the circuit is finally not that difficult, but then creating the module or synth as a real physical/mechanical thing is.

Early electronics often used point to point wiring, or [[terminal strips]]. Most modern day electronics now use [[printed circuit board]]s (PCBs) made of materials such as [[FR-4\|FR4]], or the cheaper (and less hard-wearing) Synthetic Resin Bonded Paper (SRBP, also known as phenolic, Paxoline/Paxolin (trade marks) and [[FR-2\|FR2]]).
