// To find the form factor and error
// Modern Electronic Instrumentation And Measurement Techniques

// Example 6-1 in Page 131
clear; clc; close;
// Given data
//let
E_m = 10; //Let the peak amplitude of the square wave be 10V
T = 1; //Let the time period of the square wave be 1s
function y= f(t),y=(E_m)^2 ,endfunction
E_rms = sqrt(1/T * intg(0,T,f));
printf("(a) The rms value of the square wave = %d V \n",E_rms);
function x = ff(t),x =(E_m) ,endfunction
E_av = (2/T * intg(0,T/2,ff));
printf(" The average value of the square wave = %d V\n",E_av);
k = E_rms/E_av;
printf(" The form factor of the square wave =%d\n",k);
k_sine = 1.11;
k_square = 1;
%error = (k_sine - k_square)/k_square*100;
printf("(b) The percentage error in meter indication = %d %%",%error);
//Result
// (a) The rms value of the square wave = 10 V
// The average value of the square wave = 10 V
// The form factor of the square wave =1
// (b) The percentage error in meter indication = 11 %
