Abstract: In an analysis-by-synthesis speech coder employing a short-term perceptual weighting filter with transfer function W(z)=A(z/.gamma..sub.1)/A(z/.gamma..sub.2), the values of the spectral expansion coefficients .gamma..sub.1 and .gamma..sub.2 are adapted dynamically on the basis of spectral parameters obtained during short-term linear prediction analysis. The spectral parameters serving in this adaptation may in particular comprise parameters representative of the overall slope of the spectrum of the speech signal, and parameters representative of the resonant character of the short-term synthesis filter.

Abstract: A hitch for a horse-drawn vehicle, which includes a single shaft (2) passing over a horse's back and connected at its front end to a harness (5, 6, 7) via a traction cradle (4) on which the single shaft (2) is rotatably mounted, and at its rear end to a horse-drawn vehicle (3). The cradle (4) comprises two arcuate frame members (9, 10) interconnected at their bottom ends for connection with a collar (5) to the harness and diverging progressively from each other to reach a maximum separation vertically above the horse's withers. An element (11) integral with the single shaft (2) is rotatably mounted on a member (12) interconnecting the two frame members (9, 10) at their point of maximum separation. The cradle rests on the horse's back via two pads (15, 16) swivel-mounted on the rear frame member (10) and situated on either side of the midline of the horse's back. The single shaft (2) carried by the cradle (4) is connected to a wheeled vehicle (3) via a shock absorber suspension.
