Answer:
i). Signed magnitude
Five bit representation = 11111
For positive 5 bit representation = 01111 = +15
For negative 5 bit representation = 11111 = -15
ii). One's complement
For positive 5 bit representation = 01111 =+15
For negative 5 bit representation = 10000 = -15
iii). Two's compliment
For positive 5 bit representation = 01111 = -15
For negative 5 bit representation = 10001 = +15
