Question

Consider the eight bit signed binary number 1110 0101. Convert it to signed decimal from assuming the signed binary number is represented using signed magnitude.

Answer 1

-101

Step-by-step explanation:

we can represent numbers in 2 ways signed numbers and unsigned numbers. Unsigned numbers represent only positive numbers and signed numbers represent both positive and negative numbers

In the given binary number 1110 0101, the left most bit indicates the sign. If left most bit is 1 it is negative number and if it is 0 then positive number. For the remaining bits you have to multiply the each bit with power of 2 based on the bit place/position it represents. start from left and go till before the left most bit.
