Sign magnitude representation

Binary numbers could be unsigned numbers (only positive) or signed (positive &negative)

The signed binary numbers differentiate between the positive and negative binary numbers using sign magnitude form, one's complement form, two's complement form.

This video covers the details of sign-magnitude form.

This video explains how positive and negative binary numbers are represented using the sign-magnitude form.

The sign-magnitude form uses an extra bit, the sign bit. The sign-bit is 0 for positive numbers and 1 for negative numbers.

This video provides some exercise problems regarding the sign-bit. Such conversion questions could be expected in competitive exams.

This video explains the conversion of a binary number into sign magnitude form and vice versa.

The Range of sign-magnitude numbers is also explained.
