Distortion [Signal Processing]

Description

Use case: Signal processing or system performance evaluation
When to use: Measures how much signal degradation or alteration occurs during processes like data compression, reconstruction, or transmission. It's typically used in communication systems, image/audio processing, or multimedia applications.
Key property: It quantifies how similar or different the output signal is from the original, typically in tasks where preservation of signal integrity is important.
Common measures for distortion:
- Mean Squared Error (MSE)
- Peak Signal-to-Noise Ratio (PSNR)
Example applications:
- Assessing audio or video compression quality
- Measuring fidelity in reconstructed images
