Abstract :
A new phase-modulation device with simple structure and high reliability was constructed using a short amorphous wire. A high-frequency ac current (carrier) and a signal current are simultaneously passed through the wire, which undergoes the large Barkhausen effect when the circumferential flux changes. Highly linear modulation characteristics were obtained up to 0.67¿ using a triangular-wave ac current, passed through tension-annealed wire 30 ¿m in diameter and 5 mm in length. This simple yet reliable phase modulation device is expected to find applications in the field of factory automation communication networks.
