Across
- 3. A function that conveys information over time or space
- 5. Sampling theorem states that the sampling frequency should be at least twice the signal's bandwidth
- 7. Mathematical operation used in filtering and signal processing
- 8. Type of filter with no feedback, often used in audio processing
- 9. Independent variable in the domain of signal processing
Down
- 1. Filter with feedback, known for its recursive structure
- 2. Occurs when a signal is undersampled, leading to false frequencies
- 4. Transform used to analyze the frequency content of a discrete signal
- 6. Representation of a signal's frequency content
- 8. Fast algorithm for computing the DFT efficiently
