A combined anti-noise pickup combines several anti-noise pickups together, location and relative relation of anti-noise pickups can be adjusted and determined by a common mode signal suppression circuit mounted on a bearer. Anti-noise ability of the combined anti-noise pickup is enhanced more than one times than that of a single pickup, the combined anti-noise pickup has a higher SNR performance even in a high noise environment.
L'invention concerne un enregistreur combiné à un dispositif antibruit. Un circuit de rejection en mode commun sur lequel repose cet enregistreur combiné au dispositif antibruit est chargé de commander et de définir avec précision leur positionnement et leur relation. La fonction antibruit de cet enregistreur combiné au dispositif antibruit est deux fois supérieure à celle d'un enregistreur seul. Par ailleurs, même soumis à un environnement plus bruyant, cet enregistreur fait preuve d'un rapport signal-bruit relativement bon.
