What is signal processing?
Q: What is signal processing?
A: Signal processing is the analysis, interpretation, and manipulation of signals, including sound, images, biological signals like ECG, radar signals, and many others.
Q: What are some examples of signals of interest in signal processing?
A: Some examples of signals of interest in signal processing include sound, images, biological signals such as ECG, radar signals, and many others.
Q: What does processing of signals involve?
A: Processing of signals involves the storage and reconstruction, separation of information from noise (e.g., aircraft identification by radar), compression (e.g., image compression), and feature extraction (e.g., converting text to speech).
Q: Can signals be stored and reconstructed during signal processing?
A: Yes, storage and reconstruction are involved in signal processing.
Q: What is noise in signal processing?
A: In signal processing, noise refers to unwanted information that can interfere with the signal of interest.
Q: How is information separated from noise during signal processing?
A: Information is separated from noise during signal processing using techniques like filtering and signal enhancement.
Q: What is feature extraction in signal processing?
A: Feature extraction is a process in signal processing where specific information or characteristics are extracted from a signal, such as converting text to speech.
