a. Fill in the bit pattern for the following 4-bit numbers. If there are multiple bit patterns for a number, write them all. If no bit pattern exists, write "N/A" in the box.
Unsigned, sign/magnitude, one's complement, two's complement
for 0,7,-1, 15, and 8.
I figured out those for 0, -1 and 15.
I need help on 7 and 8.
