Abstract
A comparator circuit compares two temporally separated input bursts of signals which occur at two different frequencies. The first burst is an interrogation pulse and the second burst is a reply pulse in a DME system. The comparator circuit includes a first frequency converter (CO1) for receiving at an input thereof the two input bursts, and a comparing device (DC) connected to receive an output of the first frequency converter (CO1). In order to reduce the measurement errors, the first frequency converter (CO1) receives at the input thereof the two input bursts and converts them into two new bursts of signals that have a common frequency so that the comparing device (DC) can carry out the comparison at the common frequency.
