  1. T=1/f=1/10=0.1 sec

  2. amazing <3

  3. Why is I sub f (current) flowing to R sub f opposite the convention shown in video 2 of 28? Which shows current flowing from op amp output back to the inverting input. I'm guessing typical op amp impedance on both are 1M, so it would seem as though the current flow direction should be the same direction for both. Or is this a math convention in which one has to memorize i.e inverting vs summing amplifier current flow math conventions.

  4. if we pass the output of an inverting op amp through another op amp of gain 1, will it make the original input signa positive? I mean, does connecting two inverting op amps in series, of gains= 1 outputs a positive signal ?

  5. I couldn't understand this question

  6. How is the strength of the output signal 1/2 of the input signal? @2:22
