4 cards from this section. Quick, good the night before a test.
Define latency and why it is important in real-time systems.
Think about how delays affect user experience.
What is the maximum frequency that can be sampled according to the Nyquist theorem?
Remember: it's all about those frequencies!
What is latency in real-time signal processing?
Related to how fast systems need to react.
Sampling below the Nyquist limit leads to?
What happens when you don't sample often enough?
Design a real-time signal processing system that incorporates the ideas of sampling, quantization, and anti-aliasing. Discuss how each factor affects your system's performance?
Consider a practical application like audio recording.
Develop a MATLAB function that simulates both under-sampling and appropriate sampling for a given signal. Explain the effects you observe in terms of aliasing.
Utilize the 'downsample' function to see the differences.
