• Digital

What are the steps that an ADC takes to convert an analog signal?

• Sound capture, Sound transfer, Digitization

• Discrete capture, Longitudinal Division, Quantizer

• Sampling, Quantization

• Electromagnetic Induction, Right Hand Rule

In our discussion of a cell phone, how is the change in voltage created that heads to the ADC?

• A coil and magnet creates sound waves which then lead into the wires

• The magnet generates electricity by generating sound which is then converted into induction

• Sound becomes a wave and then is captured by the ADC and turned into Electricity

• The Kinetic Energy of sound is converted into Electrical Energy from the microphone coil and Magnet

What does Sampling represent in an ADC?

• The rate of taking measurements of the amplitude of voltage

• The amount of precision among the values being measured

• Snippets of different songs being used in the creation of new song beats.

What does Quantization represent in an ADC?

• The rate of taking measurements of the amplitude of voltage

• The amount of precision among the values being measured

• Snippets of different songs being used in the creation of new song beats.
