Abstract

PURPOSE: To provide a phase-lack detecting device with a reduced number of parts and increased reliability, by constructing the device circuit such that a phaselack detection output is produced only when a phase-lack occurs and thus omitting a discrimination circuit etc. required in the prior art device.
