INTRODUCTION Digital electronics is classified into combinational logic and sequential logic. Combinational logic output depends on the inputs levels‚ whereas sequential logic output depends on stored levels and also the input levels. A sequential circuit is specified by a time sequence of inputs‚ outputs‚ and internal states. There are two types of sequential circuits. Their classification depends on the timing of their signals: * Synchronous sequential circuits - This type of system uses

. Moletronics is expected to touch almost every aspect of our lives‚ right down to the water we drink and the air we breathe. Experimental work has already resulted in the production of molecular tweezers‚ a carbon nanotube transistor‚ and logic gates. Theoretical work is progressing as well. James M. Tour of Rice University is working on the construction of a molecular computer. Researchers at Zyvex have proposed an Exponential Assembly Process that might improve

Basic Logic GatesBasic Logic Gates All digital systems can be constructed by only three basic logic gates. These basic gates are called the AND gate‚ the OR gate‚ and the NOT gate. Some textbooks also include the NAND gate‚ the NOR gate and the EXOR gate as the members of the family of basic logic gates. The descriptions of the operations of these gates are listed below: AND gate The AND gate is a circuit which gives a high output (logic 1) if all its inputs are high. A dot () is used to indicate

"Ladder" diagrams Ladder diagrams are specialized schematics commonly used to document industrial control logic systems. They are called "ladder" diagrams because they resemble a ladder‚ with two vertical rails (supply power) and as many "rungs" (horizontal lines) as there are control circuits to represent. If we wanted to draw a simple ladder diagram showing a lamp that is controlled by a hand switch‚ it would look like this: The "L1" and "L2" designations refer to the two poles of

Python and the Holy Grail Logic affects our lives everyday. We use it both subconsciously and consciously to make decisions which can be as important as our careers‚ or as insignificant as what to eat for lunch. Logic can also be used in other ways. Ironically‚ others’ bad logic can result in us learning something just as much as we learn from our own bad decisions. This is shown in Monty Python’s Quest for the Holy Grail. One example of this ironic use of logic is with the trial of the witch

Logic on a New Level In 1995‚ a talk show host‚ by the name of Rush Limbaugh was quoted while responding to a newspaper article written about a study completed by the NCEA (National Center for Economic Alternatives). According to this newspaper article‚ the study done by the NCEA claimed that American farmers use chemical fertilizers‚ and that due to our large economy‚ small businesses‚ and families‚ America is a waste generating country. Therefore‚ the purpose of this essay is to analyze the logic

PHIL1010:901 Introduction to Logic 20111:1 “What did Aristotle contribute to the discipline of Logic?” Aristotle was a Greek philosopher that lived from 384 BC to 322 BC. Aristotle was born in Stagira in northern Greece and he was the son of Nichomachus. In 367 he was sent to Athens to study philosophy with a great Greek philosopher named Plato. Some years later he traveled to Macedonia to tutor Alexander the Great. Aristotle returned to Athens and set up a school of his own following his success
