//Given Data
Rl=2D3;//Load resistance in ohms
esp=50;//Input signal voltage magnitude in volts peak
esf=314/(2*%pi);//Input signal frequncy in hertz
Vr_to_Vdc=6/100;//Ratio of peak to peak ripple voltage to d.c. output voltage
//Solution
//Using figure E3.4
//From right angled triangle pqr
C=1/(esf*Rl*Vr_to_Vdc)*10^6;//Capacitance in micro faraday;
printf("The size of filter capacitor is C = %.1f μF",C);
//Decimal errors in textbook due to approximations
