Abstract: Un amplificateur de grande puissance (1) à bande large hf, reçoit un signal d'entrée au niveau de son entrée, par l'intermédiaire d'un couplage (7), lorsqu'un signal à amplifier est appliqué à la borne d'entrée (15). La sortie de l'amplificateur (1) est capté par un coupleur (8) et est transmise à une entrée d'un comparateur (3). Le signal d'entrée appliqué à la borne (14) est transmis à une seconde entrée de comparateur (3) par l'intermédiaire d'une ligne de temporisation (5), agencé pour introduire une temporisation sensiblement égale à celle de l'amplificateur de puissance (1). Le comparateur (3) produit ainsi, au niveau de sa sortie, un signal d'erreur représentatif de la différence entre le signal d'entrée transmis par l'intermédiaire du chemin amplifié et temporisé. Un multiplexeur (16) sert à introduire le signal d'erreur amplifié dans le signal de sortie de l'amplificateur, de sorte que le signal d'erreur est en anti-phase avec ce dernier. Le signal obtenu, produit au niveau de la borne de sortie (4) a ainsi reçu une annulation de distorsion à action directe. L'agencement comprend également des réseaux de compensation (8, 9) commandés par des signaux représentant ladite torsion d'amplitude et de phase, introduites par l'amplificateur de puissance (1). Les boucles de retroaction sont agencées pour fonctionner avec un temps de réponse court, permettant ainsi d'obtenir une correction de ladite distortion de l'amplificateur, laquelle peut être supplémentaire à l'équilibrage en amplitude et en phase de réponse lente de l'art antérieur.

Abstract: The normally static, fixed gear shift speed of an internal combustion engine, at which the engine valve timings are varied in the form of the valve overlap between inlet valve and outlet valve, is shifted in the proposed method as a function of the dynamics of the acceleration process by a dynamics-related differential speed. The method thereby minimises the mis-matching between combustion engine speed and the possible torque which occurs due to a time interval necessary for modifying the engine valve timings.

Abstract: An arrangement is proposed for supplying energy to a load (1) having a low-pass frequency characteristic. A binary signal (Vld; Vlb) having a low-frequency component (Hld; Hlb) and a strong high-frequency component (Hhd; Hhb) having a predetermined frequency (1/2τ; 1/8τ) is then applied to a rejection filter (3) adjusted to the predetermined frequency (1/2τ, 1/8τ). The rejection filter (3) is of a type producing a ternary output signal. 
     The load (1) is supplied by means of a control circuit (4) in such a way that in response to the signal level at the output of the rejection filter (3) the load (1) is supplied with a positive polarity, is supplied with a negative polarity or the energy supply to of the load (1) is interrupted. In this manner energy supply is obtained in which dissipation in the control circuit (4) and load (1) is small.
