use a comparator with one input grounded i.e. a zero crossing detector to convert the sine wave to square wave....
FIRST OF ALL,
THANKS A LOT FOR LENDING HELPING HANDS.
I THINK I COULD NOT MAKE YOU UNDERSTAND GUYS!!!
AS SHOWN IN FIG BELOW I HAVE CLIPPED SINE WAVE AND I HAVE TO CONVERT IT TO SQUARE WAVE FOR COUNTING ITS FREQUENCY.
ANY IDEA GUYS??????@?!
TO:A.Anand Srinivasan &IanP
WHEN I MAKE ONE INPUT GROUND OF COMPARATOR OPAMP;THIS MEANS REF VOLTAGE IS 0V;
AND MAKE INPUT TO THE OTHER END THE CLIPPED SINE WAVE (SEE BELOW)
WILL I GET SQUARE WAVES WITHOUT EXTRA CIRCUITRY???

CAN YOU SUGGEST A SPECIFIC CONFIGURATION OF SCHMITT TRIGGER LOOKING ABOVE;
AS I TRIED SCHMITT TRIGGER BUT IN VAIN;
WAITING... EAGERLY
THANK YOU
