FOURIER ANALYSIS WITH THE TI 59 CALCULATOR.

Improved techniques and computer programs are presented of Fourier analysis with help of T159 calculator. The program is loaded from a magnetic card, the data points are keyed in only once and thereafter are stored for use. While the machine remains switched on, the data remains within until another set is entered, and it is possible to return again and again to display any of the results which have not been noted when first calculating them.
