θ is the angle by which S 2 lands S 1.If β 1 = β 2 =90 o, the comparator is called cosine comparator and if β 1 =0 and β 2 =180 o, it is a sine comparator. In short, a phase comparator compares two input quantities in phase angle (vertically) irrespective of the magnitude and operates if the phase angle between them is < 90o. There are two types of phase comparators:

a decade ago. Across the country people with low incomes are now adopting cellular phones as tools for enhancing their business. According to Oxford English Dictionary one of the earliest uses of word ‘mobile’ was in association with the Latin phrase ‘mobile vulgus’, i.e. excitable crowd. Today’s mobile phones live up to these origins.
