3 cards from this section. Quick, good the night before a test.
What is sampling in the context of signal processing?
Think about how analog signals are turned into digital signals.
What is aliasing?
It's the result of undersampling.
What is the Nyquist Theorem?
Consider the relationship between frequency and sampling.
True or False: Oversampling always improves the quality of a digital signal.
Think about the trade-offs in data processing.
You are tasked with recording a high-frequency audio signal (4000 Hz) using a digital recorder. What minimum sampling frequency should you use, and why?
Remember the Nyquist rate.
Design a simple system for audio signal processing that includes filters. Discuss the implications of sampling frequency choices on system performance.
Explore the balance between data quality and processing capability.
