4 Bit Comparator Logic. The integrated circuit ic available for 4 bit digital comparator is ic 7485. For more bit comparison more than one such ics can be cascaded.
A 4 Bit Comparator Circuit The Natures Of The Pseudo Random And Random Download Scientific Diagram from www.researchgate.net
So we will do things a bit differently here. In a 4 bit comparator the condition of a b can be possible in the following four cases. Therefore the truth table of the 4 bit comparator is the following table below.
This is shows circuit diagram for 4 bit comparator.
Explanation of 4 bit magnitude comparator a comparator used to compare two binary numbers each of four bits is called a 4 bit magnitude comparator. For more bit comparison more than one such ics can be cascaded. From the table above the logic expressions of each output are. So we will do things a bit differently here.
