Re: Quad 303
Noise issues get more complex when reactive source impedances get involved (achtung! bad pun alert!)
The RF world has had to handle this issue. Reactive impedances are free of thermal noise, but the noise behaviour of an active device is affected by them, so RF devices (well-documented ones at least!) have Smith charts of complex source impedance with contours of constant noise figure plotted on them.
