• What are the two possible inputs for a NOT gate?

  0 and 1
• How many inputs and outputs does a NOT gate have?

  One input and one output
• What feature distinguishes the NOT gate symbol?

  It has a bubble at its output
• What does a NOT gate do to its input?

  • Inverts the input
  • If input is 0, output is 1
  • If input is 1, output is 0
• What do high and low logic levels represent in digital electronics?

  Different voltage ranges
• What is the purpose of the resistors (R1, R2, R3, R4) in the Practical Inverter (NOT) circuit?

  To control the flow of current in the circuit
• How does the Practical Inverter (NOT) circuit work?

  • When the input is high, Q1 and Q4 turn on, while Q2 and Q3 turn off
  • This allows current to flow through R4 to the output, producing a low output
  • When the input is low, Q2 and Q3 turn on, while Q1 and Q4 turn off
  • This allows current to flow through R3 to the output, producing a high output
• What are the key differences between a Practical Inverter (NOT) circuit and a simple NOT gate?

  • Practical Inverter has more components (transistors, diodes, resistors) for better performance
  • Practical Inverter can handle higher power levels and provide better noise immunity
  • Simple NOT gate is a more basic logic gate with fewer components
• What is the purpose of an inverter circuit in digital circuits?

  To create a physical implementation of the NOT gate
• What is the name of the circuit shown in the image?

  Practical Inverter (NOT) circuit
• What is the purpose of the Practical Inverter (NOT) circuit?

  To invert the input signal and produce the opposite output
• When is the logic level considered low?

  When voltage is between 0V and 2V
• What is the relationship between the triangle and circle in the image?

  • The circle is positioned inside the triangle
  • The shapes are arranged in a specific geometric pattern
• How could this image be used in a visual design or logo?

  • The simple, minimalist shapes could be used in a modern, abstract logo design

• How does the output line extend from the NOT gate symbol?

  It extends from the right point with a bubble
• What is the voltage range for a high logic level?

  3-5 V
• How does a NOT gate function in a light switch scenario?

  • Switch off (0): Lamp on (1)
  • Switch on (1): Lamp off (0)
• What is the output of A AND NOT B when A = 0 and B = 1?
