Title (EN) ULTRASOUND RECEIVER CIRCUITRY AND RELATED APPARATUS AND METHODS
(FR) ENSEMBLE DE CIRCUITS DE RÉCEPTEUR D'ULTRASONS AINSI QU'APPAREIL ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) Methods and apparatus are described for implementing a coding scheme on ultrasound signals received by a plurality of ultrasonic transducers. The coding, and subsequent decoding, may allow for multiple ultrasonic transducers to be operated in a receive mode simultaneously while still differentiating the contribution of the individual ultrasonic transducers. Improved signal characteristics may result, including improved signal-to-noise ratio (SNR).
(FR) La présente invention concerne des procédés et un appareil permettant de mettre en œuvre un schéma de codage sur des signaux ultrasonores reçus par une pluralité de transducteurs à ultrasons. Le codage, et un décodage ultérieur, peuvent permettre à de multiples transducteurs à ultrasons d'être mis en même temps en fonctionnement en mode réception tout en différenciant la contribution des transducteurs à ultrasons individuels. De meilleures caractéristiques de signal peuvent en résulter, y compris un meilleur rapport signal sur bruit (SNR pour Signal-to-Noise Ratio).
