ABSTRACT:
The invention includes an apparatus and method for testing an electronic signal path. The apparatus includes a signal generator (102) configured to inject a test signal into the electronic signal path at an injection point when coupled to the signal path. The apparatus further includes a detector (104) coupled to the signal generator and configured to receive a combined signal at the injection point when coupled to the electronic signal path and determine an autocorrelation of the combined signal. The apparatus further includes an analyzer coupled to the detector and configured to determine a characteristic of the electronic signal path from the autocorrelation. The method includes injecting (902) a test signal into the electronic signal path an injection point, receiving (904) a combined signal from the electronic signal path at the injection point, determining (906) an autocorrelation of the combined signal, and estimating (908) a characteristic of the electronic signal path from the autocorrelation.
