WebApr 20, 2015 · This is equivalent to taking the FFT of a sine wave multiplied with a square window function. The FFT spectrum is then the convolution of the sine wave frequency spectrum (an impulse function) with the square wave frequency spectrum (sinc(f).) If you change L = 16,384 so that there is no zero-padding of the signal, you will observe a … WebJul 7, 2024 · A pure sine wave with whole number frequency in a DFT will have a strictly imaginary bin value pair, while a cosine wave will be strictly real. You seem to have stated the reverse. ... $\begingroup$ So if I had a signal with two sine waves i.e. in MATLAB I add the two waveform together. One at phase shifted by 30 and the other phase shifted by 90.
Webwhere: c k [ ] is the cosine wave for the amplitude held in ReX[k], and s k [ ] is the sine wave for the amplitude held in ImX[k].For example, Fig. 8-5 shows some of the 17 sine and 17 cosine waves used in an N = 32 point DFT. Since these sinusoids add to form the input signal, they must be the same length as the input signal. In this case, each has 32 points … WebLearn more about fft, dft, phase response, sine wave .
