Q1
In a summing amplifier configuration, how is the output voltage related to multiple input voltages?
  1. Vout = Vin1 + Vin2
  2. Vout = Vin1 - Vin2
  3. Vout = (Vin1 + Vin2)/2
  4. Vout = - (Vin1 + Vin2)

Questions & Step-by-Step Solutions

In a summing amplifier configuration, how is the output voltage related to multiple input voltages?
  • Step 1: Understand that a summing amplifier takes multiple input voltages.
  • Step 2: Know that the output voltage is calculated based on these input voltages.
  • Step 3: Remember that the output voltage is negative, meaning it inverts the sum of the inputs.
  • Step 4: Learn that the output voltage is scaled by a feedback resistor, which affects how much the input voltages influence the output.
