W8 (logic Gates and binary addition) Flashcards
who the fuck are Claude Shannon?
- 1937: introduced the application of
Boolean Logic in creating digital
computing machines
when Claude Shannon date of birth and date of death?
1916-2001
who introduced the Boolean Logic?
Claude Shannon
what application was useful for creating digital computing machine?
Boolean logic
Who the fuck is the father of the modern information age?
Claude Shannon (1916 – 2001)
What is gate?
A device that performs a basic operation on electrical signals
A device that performs a basic operation on electrical signals?
gate
What is Circuits?
Gates combined to perform more complicated tasks
Gates combined to perform more complicated tasks?
Circuits
What is the Boolean expressions?
Uses Boolean algebra, a mathematical notation for expressing two-valued logic
Uses Boolean algebra, a mathematical notation for expressing two-valued logic
Boolean expressions
What is Logic diagrams?
A graphical representation of a circuit; each gate has its own symbol
A graphical representation of a circuit; each gate has its own symbol?
Logic diagrams
what is the Truth tables?
A table showing all possible input values and the associated output values
What is the Functional notation
Uses a function name followed by a list of arguments in place of the operands
used in Boolean expressions
Uses a function name followed by a list of arguments in place of the operands
used in Boolean expressions?
Functional notation
What is the transistor?
Trans-conductance Variable Resistor
there are a few
other types, differing in speed, power consumption, polarity, etc.
what is transistor use for?
A transistor can act as a switch or gate for electronic signals, opening and closing an electronic gate many times per second. It ensures the circuit is on if the current is flowing and switched off if it isn’t. Transistors are used in complex switching circuits that comprise all modern telecommunications systems.
what are the two main roles of transistor?
1) Amplifier
2) binary Switch
what does amplifier used for?
An amplifier is an electronic device that increases the voltage, current, or power of a signal. Amplifiers are used in wireless communications and broadcasting, and in audio equipment of all kinds. They can be categorized as either weak-signal amplifiers or power amplifiers.
what does binary switch used for?
Binary pressure switches provide a simple and effective option for AC system pressure control. The pressure switch typically disconnects power supply to the compressor clutch to protect the compressor during abnormally high system pressure conditions and abnormally low system pressure conditions.
name all types of gate we have?
1) NOT
2) AND
3) OR
4) XOR
5) NAND
6) NOR
- There are 4 possible unary (one-input) operations
We consider one - There are 16 possible binary (two-input) operations
We consider only some of the most practically
useful ones
What colour is the logic diagram?
Typically, black and white with gates distinguished only by their shape
