Definition

What is it?

In logic and computer science, 'Excited' means a component or system is in an active, 'ON' state, ready to perform its function. It's like a light switch being turned on, allowing electricity to flow. When something is 'Excited', it has received the necessary input or signal to become active.

Simple Example

Quick Example

Imagine your mobile phone's screen. When you press the power button, the screen 'Excites' and lights up, ready for you to use. Before that, it was 'Not Excited' or 'OFF'.

Worked Example

Step-by-Step

Let's say we have a digital sensor that detects if a cricket ball crosses a boundary line. The sensor needs to be 'Excited' to work.

1. The sensor is initially 'OFF' or 'Not Excited'. It's waiting for a signal.
2. A signal (like electricity) is sent to the sensor to activate it.
3. The sensor receives this signal.
4. Now, the sensor becomes 'Excited' and is 'ON'.
5. If a cricket ball crosses the line, the 'Excited' sensor will detect it and send a signal to the umpire.

Answer: The sensor is 'Excited' when it receives the activation signal and is ready to detect the ball.

Why It Matters

Understanding 'Excited' is crucial in building any electronic device or computer program. It helps engineers design circuits that turn on at the right time. This concept is used by software developers, robotics engineers, and even in smart home technology to make things work automatically.

Common Mistakes

MISTAKE: Thinking 'Excited' means something is physically moving or making noise. | CORRECTION: 'Excited' in logic just means a component is active or 'ON', even if it's silent or still.

MISTAKE: Confusing 'Excited' with 'working perfectly'. | CORRECTION: An 'Excited' component is 'ON' and ready, but it might still have a problem. Being 'Excited' is about its state, not its performance.

MISTAKE: Believing 'Excited' is always a permanent state. | CORRECTION: A component can be 'Excited' for a short time and then become 'Not Excited' (OFF) again, just like a blinking light.

Practice Questions

Try It Yourself

QUESTION: If a traffic light changes from red to green, which state is the green light in? | ANSWER: The green light is 'Excited' (ON).

QUESTION: Your TV remote control has batteries. When you press a button, does the remote become 'Excited' to send a signal? Explain why. | ANSWER: Yes, when you press a button, the remote becomes 'Excited' because it activates its internal circuit to send the infrared signal to the TV.

QUESTION: A security camera is set to record only when it detects motion. Is the camera 'Excited' all the time, or only when motion is detected? | ANSWER: The camera's motion detection feature is 'Excited' only when motion is detected, triggering it to record. The camera itself might be in a low-power 'Excited' state (ON) waiting for motion, but its recording function only 'Excites' upon detection.

MCQ

Quick Quiz

What does it mean for a logic primitive to be 'Excited'?

It is broken and needs repair.

It is in an active, 'ON' state, ready to perform its function.

It is vibrating rapidly.

It is making a loud noise.

The Correct Answer Is:

Option B correctly defines 'Excited' as being in an active, 'ON' state. The other options describe physical properties or malfunctions, which are not what 'Excited' means in a logical context.

Real World Connection

In the Real World

Think about the automatic street lights in many Indian cities. They have light sensors that become 'Excited' (active) when the ambient light drops below a certain level (like at sunset). This 'Excited' state then triggers the street lights to turn on automatically. This is a basic form of automation used in smart city projects.

What to Learn Next

Now that you understand 'Excited', you can explore 'Not Excited' or 'De-excited', which is the opposite state. Then, you can move on to 'Logic Gates' like AND, OR, and NOT, which use these 'Excited' and 'Not Excited' states to perform complex operations in computers.
