KCC's Quizzes AQQ280 about a relaxation oscillator with a double wipers potentiometer

1. Quote of the week: "Whatever you do, always give 100%. Unless you're donating blood" - Bill Murray

 

2. New quiz AQQ280:

The circuit here below is a relaxation oscillator using a double wipers potentiometer.

The opamp is considered ideal (i.e. infinite open loop gain, infinite input impedances, zero output impedance).

 Questions:

  1. What’s the frequency at Vout for a = 1/3 and b=2/3?
  2. Same question as above but for a=10% and b=90%
  3. What happens (i.e. Vout) if the 2 inputs of the MUX are swapped (i.e. a selected when S=1 and b selected when S=0) ?

Good luck and try to be among the first ones!

If you know friends or colleagues who should participate to the quiz, please let them know ((3) Add Discussion - Quizzes - Logic Lounge - EngineerZone) !
