21. But this was proven to be incorrect after the rediscovery of Al-Kindi's book on frequency analysis . 22. Gabor's work in this and related areas was foundational in the development of time frequency analysis . 23. Examples of data compaction methods are the use of fixed-precision coding, frequency analysis , and probability analysis. 24. See Transformation between distributions in time-frequency analysis . 25. Based upon frequency analysis of the observed light curve, the star's variability exhibits multiple periods of pulsation. 26. When analysing field data with random variation a proper application of regression and frequency analysis is necessary. 27. For accurate frequency analysis , each of the 36 letters of Table 1 gets its frequency counted independently. 28. This is known as frequency analysis . 29. *" A DSP Algorithm for Frequency Analysis " ( Embedded Systems Programming, United States, January 15, 2004 ). 30. All these bilinear distributions are inter-convertible to each other, cf . transformation between distributions in time frequency analysis .
