hello,
please i need help with analyzing this circuit it has a comparator with open drain output, so it acts as a schmitt trigger and i know that when the input is greater than the high threshold the output will be low (0 volt) but if the input is less than the low threshold the output will be high (5 volt) but the problem is i do not know how to calculate these threshold levels. you will find attached an image of the circuit. thank you.
