DIGITAL ELECTRONICS

• Review of number systems, binary codes, error detection and correction codes. Digital Logic Families - Introduction to RTL, DTL, TTL, ECL and MOSL families - wired and operation, characteristics of digital logic family - comparison of different logic families

• Combinational logic - representation of logic functions-SOP and POS forms K-map representations-minimizationusing K maps - simplification and implementation of combinational logic - multiplexers and demultiplexers - code converters, adders, subtractors.

• Sequential logic- SR, JK, D and T flip flops - level triggering and edge triggering - counters - asynchronous and synchronous type - Modulo counters - Shift registers - Ring counters.

• Synchronous Sequential Logic circuits-state table and excitation tables-state diagrams-Moore and Melay models-design of counters-analysis of synchronous sequential logic circuits-state reduction and state assignment.

• Asynchronous sequential logic circuits-Transition table,flow table-race conditions-circuits with latches,analysis of asynchronous sequential logic circuits-introduction o design –implication table-hazards-programmable logic array and devices
