Question

.For 3 input inverting averaging circuit which modification is required to be made in inverting summing amplifier? *

Answer 1

Answer:

Explanation:

Thus for a 3-input non-inverting summing amplifier configuration, setting the closed-loop voltage gain to 3 will make Vout equal to the sum of the three input voltages, V1, V2 and V3. Likewise, for a four input summer, the closed-loop voltage gain would be 4, and 5 for a 5-input summer, and so on.

Answer 2

Answer:

Working principle. A summing amplifier is an example of an inverting amplifier with multiple inputs, enabling to effectively add several individual input signals, which proves to be useful in audio mixing applications.
