  • Patent number: 4450531
    Abstract: The method for the automatic electronic recognition of a program unit broadcast by radio waves includes the formation of a plurality of reference signal segments from the program unit and the processing of such segments to obtain digitized reference signal segments which are then normalized and stored. When the program unit is broadcast, the broadcast signal is processed to generate successive digitized broadcast signal segments which are correlated with the digitized, normalized reference signal segments to obtain correlation function peaks for each resultant correlation segment. The spacing between the correlation function peaks for each correlation segment is then compared to determine whether such spacing is substantially equal to the reference signal segment length.
