Harold Black and Invention of Negative Feedback Amplifier

[amirm]

Negative feedback has well, a negative reputation among audiophiles. But it is one of the most important circuit topologies in use today. You probably can't go through a single day without it being used in all manner of devices. It corrects for distortion in electronic circuits in a simple and very elegant way. Hard to imagine it was not invented prior to Harold Black at AT&T Bell Labs inventing it.
