Q1 (a) Assume that all binary numbers stated in (i) and (ii) below, are in two's complement form. (i) Convert (-477)10 into its equivalent 10-bit binary representation, [ 4 marks ] (ii) Compute the 8-bit result of 1100 10102 - 1010 10112 [6 marks (b) Obtain a Boolean expression for the output Y in the circuit shown in Figure Q1(b) in terms of NOT, AND and OR operations only. (9 marks A B Y Figure Q1(b) (c) A circuit is required to switch two digital input signals, namely A and B, dependent on a control signal C. When the control signal C is LOW(0), the output signal Y is the same as the signal A. Conversely, if the control signal C is HIGH(1), the output signal Y = ( AB) instead. Write down the truth table for Y in terms of A, B and C. [ 6 marks ]
