Answer:A
In which amplifier the output voltage is equal to the negative sum of all the inputs?
A. Averaging amplifier B. Summing amplifier C. Scaling amplifier D. All of the mentioned
Explanation: In summing amplifier the output voltage is equal to the sum of all input. Since the total input is a sum of negative input, the amplifier is an inverting summing amplifier. 2. Determine the expression of output voltage for inverting summing amplifier consisting of four internal resistors? (Assume the value of internal resistors to be equal)
