A Signal Processing Task is an data processing task (engineering?) that focuses on signal analysis, signal modification, and signal synthesis (of signals).
- Context:
- It can (often) analyze Signal Characteristics in various domains (time domain, frequency domain, spatial domain).
- It can (often) extract Signal Features for pattern recognition and classification.
- It can (often) transform Signals between different representations using mathematical transforms.
- ...
- It can range from being a Basic Filtering Task to being a Complex Analysis Task, depending on its processing complexity.
- It can range from being a Real-Time Processing Task to being a Batch Processing Task, depending on its timing requirements.
- It can range from being a Single-Channel Task to being a Multi-Channel Task, depending on its input dimensions.
- ...
- It can Remove Noise or Reduce Noise from corrupted signals.
- It can enhance Signal Quality through digital filtering.
- It can compress Signals for efficient data storage and transmission.
- It can reconstruct Degraded Signals using restoration algorithms.
- It can generate Synthetic Signals based on specifications.
- It can perform Signal Detection in presence of interference.
- It can implement Adaptive Processing based on signal characteristics.
- ...
- Example(s):
- Audio Signal Processing, which handles sound signals (speech recognition, music processing).
- Image Processing, such as: Video Signal Processing, Medical Image Processing.
- Signal Noise Reduction, including acoustic noise cancellation and image denoising.
- Biomedical Signal Processing, which analyzes physiological signals (ECG, EEG).
- Communication Signal Processing, which manages data transmission (modulation, encoding).
- ...
- Counter-Example(s):
- Data Mining Tasks, which focus on extracting patterns from structured data rather than continuous signals.
- Signal Generation Tasks, which only create signals without analysis or modification.
- Circuit Design Tasks, which deal with hardware implementation rather than signal manipulation.

- Signal processing is an electrical engineering subfield that focuses on analysing, modifying, and synthesizing signals such as sound, images, and scientific measurements. Signal processing techniques can be used to improve transmission, storage efficiency and subjective quality and to also emphasize or detect components of interest in a measured signal.
