5 Questions
Which of the following describes the nature of analog data?
Analog data take on continuous values, such as the sounds made by a human voice.
What is the main difference between analog and digital signals?
Analog signals have infinitely many levels of intensity over a period of time, while digital signals change without a repeated pattern or cycle.
What type of data are stored in computer memory?
Digital data
What is the fundamental form of a periodic analog signal?
Sine wave
How can analog data be transmitted across a medium?
Converted to an analog signal
Study Notes
Analog Data
- Analog data is continuous, varying in intensity or amplitude, and can take on any value within a range.
Analog vs Digital Signals
- The main difference between analog and digital signals is that analog signals are continuous while digital signals are discrete and take on distinct values.
Data Storage
- Computer memory stores digital data.
Periodic Analog Signals
- The fundamental form of a periodic analog signal is a sinusoidal wave.
Analog Data Transmission
- Analog data can be transmitted across a medium through modulation, such as amplitude modulation (AM) or frequency modulation (FM).
