Engineering and manufacturing control systems

What do inputs in control systems do?

• They process signals into outputs.

• They take a signal from the real-world environment and turn it into an electrical or electronic signal.

• They store data for future use.

• They convert electrical signals into mechanical energy.

Which of the following is an example of a real-world signal?

• Voltage

• Current

• Light level

• Logic state

Which of the following is an example of an electrical and electronic signal?

• Sound

• Movement

• Temperature

• Voltage

What do blocks represent in a block diagram?

• Signals passing between components

• Components that make up each function or subsystem

• The entire control system

• The output of a process

What is the purpose of arrows in a block diagram?

• To represent the components

• To indicate the signals that pass between blocks/components

• To show the output of the system

• To label the blocks

In a block diagram, where are inputs generally shown?

• On the right-hand side

• On the top

• On the left-hand side

• At the bottom

What do the arrows in a block diagram represent?

• The size of the block

• The signals flowing in and out of the block

• The color of the block

• The shape of the block

What does the block in a block diagram represent?

• The input function or device itself

• The output function

• The power source

• The user interface

What role do processes play in control systems?

• They provide energy to the system.

• They are responsible for data storage.

• They regulate and manage system operations.

• They are used for system decoration.

Which of the following is a process device used in control systems?

• Amplifier

• Timer

• Transformer
