Digital Signal Processing (I)

frequency at will. Assume that there is a sine signal X [N], its frequency f = 100Hz, its amplitude is A, and its initial phase is 0, the signal can be expressed as follows:X (t) = A * sin (2 * pI * 100 * t)Sample it with the sampling frequency fs = Hz. The resulting digital signal X [N] is:X [N] = A * sin (2 * pI * 100 * n/Fs) = A * sin (0.4 * pI * n)Obviously,

Various frequency relations in digital signal processing

the s plane, the digital frequency still changes from 0 to 2 pi on the z-plane unit circle. 。。。。。。 The z-plane repeats like this. We know that the Fourier transform of the discrete signal corresponds to the z-transform on the unit circle , so the above conclusion verifies why the Fourier transform of the discrete signal is cyclical: the root cause is the periodicity on the unit circle.Considering

I. Discretization of the signal 1, sampling theorem:– If the signal is limited and the sampling frequency FS exceeds twice times the maximum frequency of the signal, then the original continuous signal can be completely reconstructed from the sample sample. Therefore, the sampling rate (FS) is a very important paramete

Voice Signal Processing (I) Dynamic Time normalization (DTW)

mentioned above, that is, the similarity between the series Q and C. The cumulative distance gamma (I, j) can be expressed as follows. The cumulative distance gamma (I, j) is the current point distance d (I, j ), that is, the sum of the Euclidean distance (similarity) between the vertex Qi and CJ and the cumulative distance of the smallest adjacent element that can reach the vertex: The optimal path is to make the accumulation distance along the path reach the minimum value. This path can be o

Speech signal Processing (a) dynamic time warping (DTW)

cumulative distance gamma (I,J) can be expressed in the following way, and the cumulative distance γ (I,J) is the current lattice distance d (i,j), which is the sum of the Euclidean distance (similarity) between the points Qi and CJ and the cumulative distance of the smallest neighboring elements that can reach that point: The best path is the path where the accumulation distance along the path reaches the minimum value. This path can be obtained through the dynamic Programming (programming) a
