| Abstract: | A phase-locked loop containing a voltage-controlled oscillator (v.c.o.) synchronised to a harmonic of its fundamental output frequency may be used to form an attractive digital phase shifter providing low phase error with relatively simple circuitry and control requirements. Phase increments of 2?/n radians are obtained, where n is the order of harmonic used. |
