2.2.4. Conversion between Analog and Digital Signals

Try these first

1. 1.

   What is the primary function of an analog circuit?

   Hint

   Think about the role of an amplifier.

2. 2.

   Define gain in the context of analog circuits.

   Hint

   It relates to how strong the output signal is.

3. 3.

   What is the main task of an analog circuit?

   • Rejection of signals
   • Amplification of signals
   • Digital conversion

   Hint

   Think about what amplifiers are designed to do.

4. 4.

   True or False: Frequency response describes how a circuit handles different input frequencies.

   • True
   • False

   Hint

   Consider what frequency response means.

5. 5.

   Design a practical analog circuit that uses a combination of an ADC and DAC to process an audio signal. Specify the components and explain your choice.

   Hint

   Focus on how signals transition between analog and digital forms.

6. 6.

   Evaluate a scenario where a low-pass filter is used in an audio mixing console. What frequencies need to be filtered out and why?

   Hint

   Consider what constitutes unwanted noise in audio signals.
