Stereo vinyl records encode both the left and right stereo channels in a single groove. The V-shaped groove in the vinyl has walls that are 90 degrees to each other, with variations in each wall separately encoding one of the two analogue channels that make up the stereo signal.

WebOrthogonal Time Frequency Space Modulation Arman Farhang, Ahmad RezazadehReyhani, Linda E. Doyle, and Behrouz Farhang-Boroujeny Abstract—Orthogonal time frequency space (OTFS) modula-tion is a two-dimensional signaling technique that has recently emerged in the literature to tackle the time-varying (TV) wireless channels. WebOrthonormal means these vectors have been normalized so that their length is 1. Orthogonal vectors are useful for creating a basis for a space. This is because every point in the space can be represented as a (linear) combination of the vectors. So for example in 3D space, x= [0,0,1] y= [0,1,0] and z= [1,0,0] form an orthornormal basis.
