WebIf X is a vector, then nufft returns the transform of the vector.. If X is a matrix, then nufft treats the columns of X as vectors and returns the transform of each column.. If X is a multidimensional array, then nufft treats the values along the first array dimension whose size does not equal 1 as vectors and returns the transform of each vector. http://hades.mech.northwestern.edu/index.php/PIC32MX:_FFT_of_Analog_Input

WebThe FFT is a 1024 point FFT. I am able to get the DC value in the 0th index of the frequency bin. The formula being used to get the frequency value from the bin is Frequency = index * Sampling Frequency / Number of FFT Points However, I am getting a high magnitude always in the 1st and the 2nd frequency bins for any value of the input frequency.
