When feedback isn't just feedback
I think I've been scarred for life. EE 140 has programmed a new physical response to "feedback." Two of my professors said "feedback" today. Both were in sentences asking for student comments on the pace of the class. Both times, the word sent shivers down my spine.
Feedback, as I know the term, is a technique used when designing amplifiers that allows the output to influence the input. Feedback improves the output and input impedance of the amplifier and changes the gain (closed-loop) to approximately the inverse of the feedback factor (bypassing the problem of needing precise transistor sizing). The problem is that feedback introduces stability problems. And feedback is a pain to analyze—at least, at the moment.
Miscellaneous Updates
Slight design tweak to cover short entries viewed on large monitors. Reload.
I still need to make the graphics page, make a "favorites" archive listing, write The Making of piece for the current design, and write reviews for Fantavision and UNLIMITED: SaGa.
And a new theme has been swirling around my mind for awhile.
School and job hunting are not helping. Reminders for me: AMD resumé submission deadline is the 20th. Annual career fair is next week.
