My thought is that some power could be saved by working with lower voltage during the signal processing and, if necessary, amplify it back to +-10 V in the end. text/html 2024-06-14T20:52:49+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.jegatron.se/doku.php?id=modular_synthesizers:opamp&rev=1718398369&do=diff För icke inverterande: Gain Bandwidth Product = Gain * Bandwidth För inverterande: Gain Bandwidth Product = Gain * Bandwidth / 2 Slew rate för sinus: f * Vpp/2 * pi = V/s Bandwith vs rise-time: Rise time 10-90 % = 0.35 / f Trans impedance configuration text/html 2024-08-09T14:43:50+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.jegatron.se/doku.php?id=modular_synthesizers:will_it_blend&rev=1723214630&do=diff Will It Blend?
