Abstract :
A state-sequenced polarity crosscorrelator is described which is controlled by a flexible ROM sequencing unit and uses overflow peak detection. Delay resolution from <38 ¿s down to any desired value can be accommodated. Calibration using a CCD delay line indicates delay time measurements with an accuracy of better than 2% of the reading.
