I have to do FFT in MATLAB on the digital sinusoidal data that is stored in excel. please find the amplitude values of the sine wave discrete signal stored in the Lookup table.
Number of points : 256
Maximum amplitude : 1024
Numbers per row: 1
Numbers are in decimal
512, 525, 537, 550, 562, 575, 587, 600, 612, 624, 636, 649, 661, 673, 684, 696, 708, 719, 731, 742, 753, 764, 775, 786, 796, 807, 817, 827, 837, 846, 856, 865, 874, 883, 891, 900, 908, 916, 923, 931, 938, 945, 951, 957, 964, 969, 975, 980, 985, 990, 994, 998, 1002, 1005, 1009, 1012, 1014, 1016, 1018, 1020, 1022, 1023, 1023, 1024, 1024, 1024, 1023, 1023, 1022, 1020, 1018, 1016, 1014, 1012, 1009, 1005, 1002, 998, 994, 990, 985, 980, 975, 969, 964, 957, 951, 945, 938, 931, 923, 916, 908, 900, 891, 883, 874, 865, 856, 846, 837, 827, 817, 807, 796, 786, 775, 764, 753, 742, 731, 719, 708, 696, 684, 673, 661, 649, 636, 624, 612, 600, 587, 575, 562, 550, 537, 525, 512, 499, 487, 474, 462, 449, 437, 424, 412, 400, 388, 375, 363, 351, 340, 328, 316, 305, 293, 282, 271, 260, 249, 238, 228, 217, 207, 197, 187, 178, 168, 159, 150, 141, 133, 124, 116, 108, 101, 93, 86, 79, 73, 67, 60, 55, 49, 44, 39, 34, 30, 26, 22, 19, 15, 12, 10, 8, 6, 4, 2, 1, 1, 0, 0, 0, 1, 1, 2, 4, 6, 8, 10, 12, 15, 19, 22, 26, 30, 34, 39, 44, 49, 55, 60, 67, 73, 79, 86, 93, 101, 108, 116, 124, 133, 141, 150, 159, 168, 178, 187, 197, 207, 217, 228, 238, 249, 260, 271, 282, 293, 305, 316, 328, 340, 351, 363, 375, 388, 400, 412, 424, 437, 449, 462, 474, 487, 499
I have tried writing code in MATLAB but I am not getting the exact output. lease tell me the coding procedure to obtain FFT.
