How do you align two signals in Matlab?
[ xa , ya ] = alignsignals( x , y ) estimates the delay D between the two input signals x and y , and returns the aligned signals xa and ya . The function estimates the delay using cross-correlation. If y is delayed with respect to x , then D is positive and x is delayed by D samples.
How do I set sampling rate in Matlab?
The sampling frequency or sampling rate, fs, is the average number of samples obtained in one second (samples per second), thus fs = 1/T. To sample a signal in MATLAB, generate a time vector at the appropiate rate, and use this to generate the signal.
How do you change the sample rate of a signal?
To change the sample rate from 44.1 to 48 kHz, you have to determine a rational number (ratio of integers), P/Q , such that P/Q times the original sample rate, 44100, is equal to 48000 within some specified tolerance. To determine these factors, use rat .
How do you increase the sampling rate of a signal in Matlab?
y = interp( x , r ) increases the sample rate of x , the input signal, by a factor of r . y = interp( x , r , n , cutoff ) specifies two additional values: n is half the number of original sample values used to interpolate the expanded signal.
