Challenge Problems
Push your limits with advanced challenges
Design a summing amplifier with four input voltages, V1 = 1V, V2 = 2V, V3 = 3V, and V4 = 4V using resistor values of 10k ohm for each. Calculate the output voltage.
💡 Hint: Use the summation formula considering the resistors are equal.
You need to adjust the output voltage of a summing amplifier to achieve a specific mix. If V1 = 2V, V2 = 2V, and you want a Vout of -6V, what should the resistor ratio for V2 be if R1 = 10k ohm?
💡 Hint: Rearrange the equation to isolate R2.
