Show transcribed image text 3. A 1K Ohm potentiometer is shown below. The full travel of the potentiometer is 270 degrees. a. What is the Voltage reading at 90 degrees? (10 points) b. What is the non-linearity error al 90 degrees? (5 points) A circuit consists of an-op=amp and three resistors, it the input voltage is 2V , a. What is the voltage V2? Explain why? b. What is the voltage V1? c. What is the output voltage V0? 10. A circuit is shown below. The input is a triangular wave of 15 V peak-to-peak, a. Sketch the output wave form? Explain with as much detail as possible. (5 points) b. Where should the slider be to generate a signal of duty cycle 33.3%? (10 points)
