Nettet15. jul. 2024 · And so now we have expressed the original signal as a sum of two Fourier basis vectors. So x[n] will be equal to 3 over 2 times basis vector number 4 plus basis vector number 60. At this point we can apply the DFT as an inner product with each vector in the basis, and we can exploit the linearity of the operator. NettetEquation 3-17'. As stated in relation to Eq. (3-13'), if the DFT input was riding on a DC value equal to Do, the magnitude of the DFT's X (0) output will be DoN. Looking at the real input case for the 1000 Hz component of Eq. (3-11), Ao = 1 and N = 8, so that Mreal = 1 · 8/2 = 4, as our example shows. Equation (3-17) may not be so important ...
