(a) Using a "word" of 4 bits, list all of the possible signed binary numbers and their decimal equivalents that are representable in: [6 marks]

i) Signed magnitude ii) One's complement iii) Two's complement

(b) From the results of the previous question, generalize the range of values (in decimal) that can be represented in any given x number of bits using: [6 marks]

i) Signed magnitude ii) One's complement iii) Two's complement
