Question
Matlab 6 Synthesize the sound piano eo 130.5 Fundamental frequency / Hz 67 68 69 70 71-Ts2 72-NS20 73 - 74- len-1s* fss;% length (Ys) 75- deltaf fs/len; 76-n peak 0/delta f+l: 2.2.1 Synthesize a signal that will define frequency resolution (all components same phase) duration in s number of components sampling frequency in Hz tss . 44100: - - - % distance between two samples - - % number of samples between to peaks create a vector rs ( ynthe sized) containing complex spectrum of a 5um of sinusoids 79 80Yzeros (len, 1) 81- y-pos-zeros (fix( 82 83 94 85 ) +1,1); % here we divide the NYQUIST freq by the spectral resolution and see i (fs-s/2) /delta-f % positive half (freq) of t vector we have a sample there (fix). for loop to fill in the peaks for the positive frequencies or n-L:N 20 peaks on the positive frequencies amplitude of peaks 87- 88-end 89 90 91 92 93 94 95 % check if vector is even or odd. If it is even, it will hiot the NYQUIST frequency, then the spectrum is mirrored around this - and hence it is % NOT contained in the negative frequencies. If it is odd, the NYQUIST frequency will NOT be hit, hence you have a sample symetrically around the NYQUIST frequency and need to take all but the first sample of the % positive frequencies (the DC) with you:Explanation / Answer
