Discrete Sequences
Similarly, for discrete sequences and period N, we can write the circular convolution of functions h and x as:
This corresponds to matrix multiplication, and the kernel of the integral transform is a circulant matrix.

Famous quotes containing the word discrete:
“The mastery of ones phonemes may be compared to the violinists mastery of fingering. The violin string lends itself to a continuous gradation of tones, but the musician learns the discrete intervals at which to stop the string in order to play the conventional notes. We sound our phonemes like poor violinists, approximating each time to a fancied norm, and we receive our neighbors renderings indulgently, mentally rectifying the more glaring inaccuracies.”
—W.V. Quine (b. 1908)
