Q. Explain working of Inverting Summing Amplifier?
The circuit of Figure is extended by adding other input points, as shown in Figure. Because of the virtual ground at terminal 1 (ideal op-amp assumption), the response of the circuit to any one input is not affected by the presence of the other N - 1 inputs. Based on Equation one can write the total output as the sum of all responses,
If all resistors R are the same, say R = R , for all n, then
which corresponds to an inverting summing amplifier with gain.
The resistance of a wire is 60 ? at 25 o C and 65? at 75 o C. Find the resistance of wire at 0 o C and value of temperature co-efficient at 0 o C. Ans: Given R 25 = 60 ? a
