Question 1.
What defines a discrete signal?
Show hintHide hint
Think about how measurements are collected over time.
Question 2.
What does noise in a signal refer to?
Show hintHide hint
Consider factors that can interfere with measurements.
3Question 3.
What is the key characteristic of discrete signals?
- Continuous data collection
- Data at specific intervals
- Data at random times
Show hintHide hint
Think about how the signals are measured.
4Question 4.
True or False: Noise enhances data quality.
- True
- False
Show hintHide hint
What impact does noise have on clarity?
Question 5.
You have a dataset with a signal strength of 70 and noise level of 10. Calculate the SNR. Discuss why this value is relevant for data interpretation.
Show hintHide hint
Focus on how SNR quantities the relative strength of the signal.
Question 6.
A sensor operates in a noisy environment with fluctuations causing irregular spikes. Propose a method to improve data reliability and explain its principles.
Show hintHide hint
Consider techniques that involve processing and manipulating data for clarity.
