Question

3. You have a Zener diode with a breakdown voltage of 6.3 Volts and maximum current of 10 mA. Use the diode and an op-amp to create a reliable voltage source which can be varied between 10 and 20 Volts. Indicate which resistor you would vary and its range of values to give the required voltage. 4. Determine the output voltage for $0 < t < 2\pi$. -5 V v = 0.5 V V = cos (t) +5 V V_{out} 5. Design a circuit using a 1 mF capacitor which will have $v_{out} = \frac{2}{d} \frac{dv}{dt}$
