Digital Logic SECR1013

Module 1 reflection

I learned topic of analog and digital system and also their terms that used, digital operation and functional function. Analog is continuous range of value but digital is a discrete set of value. I can ilustrate basic operation of digital logic systems. From this module also it covers the technologies of digital logic ICs and PLDs.

Module 2

In this module, I learn 2 parts which are Numbering System Code and Data representation and Basic Arithmetic Operation. I had learned the step tp illustrate the numbering system, demonstrate the process of converting a value from one numberin system to another. I know what is LSB and MSB, unsigned data, 1’s complement and 2’s compement and it also has the relation to illustrate the arithmetic computation.

Module 3

Basically module 3 is to introduce the basic gates which are (NOT, AND, OR). Derive the universal gates from basic gate for example, (NAND , NOR , XOR , and XNOR). Module 3 also covers the characteristic of each gates.

Module 4

Module 4 I learned about Boolean Algebra. I can simplify the digital citcuit using Boolean Algebra and K-MAP (Karnaugh Map). It is a little hard at first, but yeah..thanks to my friends to teach on how to do that k-Map stuff. After making the K-Map, I can apply the Boolean Algebra in designing and analyzing digital circuit.

Module 6

Module 6 got not much different with module 1 it covered deeply about functions of combinational logic. I learned and know about design of functions, Module 6 also covered the topic on how to use an MSI chip of the functions.

Module 5

From Module 5 I learned so much about the introduction of AND-OR and AND-OR-invert logic. Learned on how to illustrate the conversion between different representations of digital circuit. Next is universality of gate and dual symbol in a digital circuit. Those are for make the circuit look more simple and easy and to reduce cost.

Module 7

Basically module 7 have a relation to module 6, but more on latches and flip flop. There are 3 types of latches (SR latches , Gated SR Latches , Gated D latches). Next 4 types of latches ( SR , D , JK , T) .This module also explain about characteristic of latches and flip flop. I can illustrate the timing diagram associated with each Latches and flip Flop operations.

Module 8

Module 8 is the next part of module 7, it covered the topic to distinguish the different between synchronous and asynchronous counter. I can illustrate the designing of counters and explain the application of counters, the advantages and disadvantages for each types. Lastly I can demonstrate the analysis of sequential circuits.
