A Simple Digital Correlator
In recent years tnare has been increasing interexts incorrelation functions in such fields as automalic control and communication. One of the reason for this is that the autocorrelation function provides a statistical means for optimum setting when the input to a control system is an stationary random process. A simple digital device is described for computing the autocorrelation function and spectral density which is its Fourier tratnsform. The input function to be correlated are fed intothedoi:10.11499/sicejl1954.2.24 fatcat:xq4cancxyrguzpgrsyym2aljaq
