Question

1. All digital systems manipulate data in Binary form. But reading long strings of 0s and ones pauses a challenge in the way we process the information. Hence its always convenient for us to convert to other Binary Code forms. 1.1.Carry out the following number conversions 1.1.1. 43758 = X9 F9.D16 = Y8 [4 Marks] 1.2.Carry out the following complement operations 1.2.1. 10s complement of 856.21 BCD code [2 Marks] 1.2.2. 2’s complement of a binary number 1011.012 [2 Marks] 1.3. Convert 10101 (Gray Code) to Binary code [2 Marks] 1.4. Encrypt this data stream {11001011} using even parity hamming code. [3 Marks] Give two advantages that a digital signal has over an analogue signal
