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.
What part of a graph represents sampling?
x-axis
y-axis
What part of a graph represents quantization?
x-axis
y-axis
What is the term used to determine the quality of a quantizer?
Computing Power
Resolution
Quantization
Sampling Rate
Which one of these is NOT an example of a benefit of converting analog signals to digital signals?
Digital Signals last forever
Digital Signals are easier to use and send
Digital Signals can be used among every Digital Divice
Digital Signals can have quantization noise
