+//To find the number of pulses counted

+//example5-5 in page 131

+clc;

+//data given

+Vr=1.25;//peak voltage of ramp in volts

+tr=125e-3;//time period of the ramp=1.25 ms

+T=1/(1e+6);// frequency =1 Mhz and time period of the clock pulses is 1/f

+for Vi=0.75:(0.9-0.75):0.9,// analog input voltages for which clock pulses has to b found

+    t1=(tr/Vr)*Vi;//time period of the comparator high out put

+    N=t1/T;// pulses counted

+    printf("number of pulses counted for Vi=%.2f V are %d\n",Vi,N/100);

+end

+//result

+//number of pulses counted for Vi=0.750000 V are 750

+//number of pulses counted for Vi=0.900000 V are 900
