Parallel Subtractor

The combinatorial circuits which are used to subtract two binary numbers are called Subtractors. When the binary numbers to be subtracted are of single bits, then, we can use a half subtractor to accomplish the task while if we need to subtract three binary numbers of single bits (among which two will generally be inputs … Read more

Binary Subtractor

Before discussing about binary substractor, let us discuss about method of substracting two multi bit binary numbers. For above substraction we used general rules which are, and borrow 1 which to be added to next higher significant bit of first binary number. Then same positioned bit of second binary number would be substracted from that. … Read more
