How do you create a periodic signal in Matlab?
The periodic signal is defined by a single-cycle waveform cached as the Wavetable property of your wavetableSynthesizer object. To generate a periodic signal: Create the wavetableSynthesizer object and set its properties. Call the object with arguments, as if it were a function.
What does the Xcorr function do in Matlab?
r = xcorr( x , y ) returns the cross-correlation of two discrete-time sequences. Cross-correlation measures the similarity between a vector x and shifted (lagged) copies of a vector y as a function of the lag.
How do you calculate cross-correlation?
Cross-Correlation
It is calculated simply by multiplying and summing two-time series together. In the following example, graphs A and B are cross-correlated but graph C is not correlated to either.
How do you calculate autocorrelation function?
The number of autocorrelations calculated is equal to the effective length of the time series divided by 2, where the effective length of a time series is the number of data points in the series without the pre-data gaps.
