+//Chapter 8_Applications of Operational Amplifier
+//Caption : Vp and Vo
+//Example8.8: In the circuit of non-inverting summing Op-Amp, V1=+2V, V2=-4V, V3=+5V. input resistors for all the three input signal are same and are equal to 1 kilo Ohm.The feedback resistor Rf is 2 kilo ohm. Determine the voltage Vp at the noninverting pin of the Op-Amp and the output Vo. Assume ideal Op=Amp.
+//Solution:
+clear;
+clc;
+Rf=2*10^3;//feedback resistor
+R1=1*10^3;
+R2=R1;
+R3=R2;
+V1=2;
+V2=-4;
+V3=5;
+n=3;//no of inputs
+Vp=(Rf/R1*V1+Rf/R2*V2+Rf/R3*V3)/n;
+Vo=(1+Rf/R1)*Vp;
+disp('V',Vp,'voltage at noninverting pin is:')
+disp('V',Vo,'output voltage voltage of noninverting summing Op-Amp is:')
