what is the main purpose of individual resistors and how does its values effect in the ddesign of comparator circuit. can anyone illustrate me theoritical design?

 

Welcome to AAC

There are many kinds of comparators.
Present one or what kinda comparator are u referring to ?

 

Resistors forming a potential divider are often used to establish a reference voltage against which a test signal is compared.

 

what is the main purpose of individual resistors and how does its values effect in the design of comparator circuit. can anyone illustrate me theoretical design?

Most people will not type a 6 page, illustrated answer for you when you can search for the basic theory yourself. It has already been written. You only need to find it. When you learn enough to ask a question that can be answered with less than a whole page, you will receive good answers.

 

Sketch a schematic of the comparator circuit you have in mind, so we know what you are talking about. Be sure to label each component with a reference designator, like R1, R2, R3, etc. for resistors, C1, C2, etc. Without this information, it is almost impossible to discuss how components function in a circuit.
