Q. Mention the gate used as comparator.
Solution:
Comparators are used in central processing units (CPUs) and microcontrollers (MCUs). Examples of digital comparator include the CMOS 4063 and 4585 and the TTL 7485 and 74682.
Note: An XNOR gate is a basic comparator, because its output is “1” only if its two input bits are equal..
