+//Chapter 12_Signal Generators
+//Caption : Waveform Generator
+//Example12.20: Design a waveform generator using type 8038 IC.The frequency of Oscillation is 5 kHz and the duty cycles is 50%.From data sheet,typical values for the device at Vcc=5 V are as follws:
+//Voh=3.6 V; Vol=0.2 V; Ill=-1.6 mA and Ilh=40 uA.
+//Solution:
+clear;
+clc;
+Fo=5*10^3;
+//for 50% duty cycle Tp=Tn
+Vcc=5;//in volt
+Vol=0.2;//in Volt
+Voh=3.6;//in volt
+Ill=-1.6*10^-3;
+Ilh=40*10^-6;
+Tp=1/(2*Fo);
+C=0.01;//assuming the Capacitor value in uF for optimum design
+Ra=Tp/(1.66*C);
+Rb=2*Ra*Tp/(1.66*Ra*C+Tp);
+R2min=(Vcc-Vol)/(2*10^-3-abs(Ill));//since Ill is negative
+R2max=(Vcc-Voh)/(1*10^-6+Ilh);//since Ilh is positive
