1.2.2. Input and Output Signals

Try these first

1. 1.

   Define what an input signal is.

   Hint

   Think about what you apply to a circuit for it to work.

2. 2.

   What type of signal represents distinct levels?

   Hint

   Recall the binary system's high and low states.

3. 3.

   What is an analog signal?

   • A signal with discrete levels
   • A continuously varying signal
   • A signal with binary states

   Hint

   Think about how audio signals are represented.

4. 4.

   True or False: Digital signals can only have two states.

   • True
   • False

   Hint

   Think of a light switch's positions.

5. 5.

   Create a scenario where both analog and digital signals must be processed in a single system, explaining how each will interact.

   Hint

   Think about the devices you use in daily life that collaborate different types of data.

6. 6.

   Discuss the advantages of using digital signals over analog signals in modern systems.

   Hint

   Consider the quality and ease of use of different signals in terms of signal processing.
