What is the meaning of orthogonality in signal processing?
Can you give me an example of how this property is utilized in practice?
Yes, one example is in the processing of digital multimedia signals such as audio and video. For instance, in video compression, the video is typically encoded as a set of orthogonal components using a technique called discrete cosine transform. These components can then be efficiently compressed and transmitted without loss of quality.
