Answer the following questions:
- Represent the following two’s complement values in decimal: [5 marks]
1101011
- Show how the floating point value (1/16) would be stored using IEEE-754 single precision (be sure to indicate the sign bit, the exponent, and the significand fields) [5 marks]
- Charles Sturt University (CSU) has opened an IT Doctorate study in Sydney Study Centre. The applicant should have a master degree in IT or a master degree in electrical engineering. The applicant should also has completed project subject (e.g. ITC570, ITC571, …) in his master degree. Before CSU management staff approve student’s application, they have to check the entry requirement for the master degree and also check whether if the student has completed project subject in his master degree. After checking applicant documents, CSU staff has come to the following conclusions:
- Approve if applicant has one of the required master degrees and has completed project subject.
- Approve if applicant has two of the required master degrees and has completed project subject.
- Don’t approve otherwise.
Construct a truth table and find the minimized Boolean function to implement the logic telling the CSU staff when to approve. Draw a circuit diagram for the Boolean function. [5 marks]
- Complete the truth table for the following sequential circuit: [5 marks]
Online submission via Turnitin is required for this assignment.
