Abstract
A long phase-locked loop circuit is provided which has an electronic closure circuit in series in the loop. The loop is effectively an open loop until acquisition of the incoming signal at which time the electronic closure circuit closes the phase-locked loop. A novel coincidence circuit is provided which compares the carrier in the loop with a reference frequency and when the two frequencies are equal the coincidence circuit closes the electronic closure circuit.
