17
Q

What is the transistor?

A

Trans-conductance Variable Resistor

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

18
Q

what is transistor use for?

A

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.

19
Q

what are the two main roles of transistor?

A

1) Amplifier
2) binary Switch

20
Q

what does amplifier used for?

A

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.

21
Q

what does binary switch used for?

A

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.

22
Q

name all types of gate we have?

A

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

23
Q
A
  • 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
24
Q

What colour is the logic diagram?

A

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

25
Q

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

A

NOT gate because it inverts the input value

26
Q
A

There are some alternative notations for NOT gate

27
Q

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

A

slide 6

28
Q

why we need to use transistors?

A
  • 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
29
Q

what are the alternative of the transistors?

A
  • Relays: large, very slow
  • Vacuum tubes: fragile, consume lots of power
30
Q

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

A

Transistors

31
Q

what is the building block for modern computer microchips?

A
  • Transistors are building blocks for modern
    computer microchips
