Default The Catch-22 of Negative Feedback aka NFB


: we've been through this 'linearity contest' before, here.
: whereas you define it in terms of current amplification,
: i define it in terms of voltage amplification.
: as real-world interfacing in audio is with *voltages*,
: doesn't seem unreasonable...
:
:
: Negative feedback is generally used to make amplifiers more linear in the
: voltage domain. It's a highly sucessful strategy. We sent men to the moon,
: partially based on amplifiers that were linearized with negative feedback.



Uhhh, power amplifiers work on complex loads in the power domain?
