Module Aims
|
To provide the student with a thorough understanding of the principles and practical aspects of modern digital circuits and systems.
|
Learning Outcomes
|
On completion of this module, the student will be able to
- design combinational logic circuits & solve problems with: encoders; decoders; multiplexers; demultiplexers (PO1, PO2)
- apply computer codes: ASCII; BCD; Parity codes; Hamming codes (PO1, PO2)
- use binary and floating point arithmetic and design computer architecture components: adders; multipliers and dividers; ALU and accumulator (PO1, PO2, PO3)
- analyse and design sequential logic circuits using state diagram and state table, employing state assignment and reduction. (PO2, PO3)
- evaluate the performance of digital circuits from the TTL, ECL, IIL and MOS technologies and demonstrate knowledge about their speed, power consumption, noise margin, loading and cost. (PO1, PO3, PO6)
- distinguish among different digital storage: bistable latch; single word memory; static and dynamic RAM; ROM, organisation of memory systems. (PO1, PO2)
- design complex arrays of programmable logic devices: ROM, PLA, PAL, GAL. (PO1)
- describe and explain microprocessor interfacing: parallel I/O; serial I/O; video controllers; timers. (PO1)
- solve various engineering problems (PO2, PO3, PO5)
