Answer 9

Circuits

Question 10

What is the Boolean expressions?

Answer 10

Uses Boolean algebra, a mathematical notation for expressing two-valued logic

Question 11

Uses Boolean algebra, a mathematical notation for expressing two-valued logic

Answer 11

Boolean expressions

Question 12

What is Logic diagrams?

Answer 12

A graphical representation of a circuit; each gate has its own symbol

Question 13

A graphical representation of a circuit; each gate has its own symbol?

Answer 13

Logic diagrams

Question 14

what is the Truth tables?

Answer 14

A table showing all possible input values and the associated output values

Question 15

What is the Functional notation

Answer 15

Uses a function name followed by a list of arguments in place of the operands
used in Boolean expressions

Question 16

Uses a function name followed by a list of arguments in place of the operands
used in Boolean expressions?

Answer 16

Functional notation

Question 17

What is the transistor?

Answer 17

Trans-conductance Variable Resistor

there are a few
other types, differing in speed, power consumption, polarity, etc.

Question 18

what is transistor use for?

Answer 18

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.

Question 19

what are the two main roles of transistor?

Answer 19

1) Amplifier
2) binary Switch

Question 20

what does amplifier used for?

Answer 20

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.

Question 21

what does binary switch used for?

Answer 21

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.

Question 22

name all types of gate we have?

Answer 22

1) NOT
2) AND
3) OR
4) XOR
5) NAND
6) NOR

Answer 23

• 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

Question 24

What colour is the logic diagram?

Answer 24

Typically, black and white with gates distinguished only by their shape

Question 25

which type of gate is referred to as an inverter? and why?

Answer 25

NOT gate because it inverts the input value

Answer 26

There are some alternative notations for NOT gate

Question 27

Draw the boolean expression, logic diagram symbol, truth table for NOT gate?

Answer 27

slide 6

Question 28

why we need to use transistors?

Answer 28

• One need to be able to implement the logic
  functions in hardware
• One also needs to be able to pass the output
  of one function to an input of another
  (possibly several inputs)
• In order to perform more complex operations

Question 29

what are the alternative of the transistors?

Answer 29

• Relays: large, very slow
• Vacuum tubes: fragile, consume lots of power

Question 30

What is can be very power-efficient and very fast?

Answer 30

Transistors

Question 31

what is the building block for modern computer microchips?

Answer 31

• Transistors are building blocks for modern
  computer microchips
