Abstract: The processing of audio signals is shown in which a first gain-adjustable amplifier is configured to receive a feed forward signal from an input and a second gain-adjustable amplifier is configured to receive a feedback signal from an output. A gain controller supplies a first gain control signal to the first gain-adjustable amplifier, wherein the gain controller supplies a complementary second gain control signal to the second gain-adjustable amplifier, which may be the reciprocal of the first gain control signal. A first combiner is arranged to combine a first output from the first gain-adjustable amplifier with a second output from the second gain-adjustable amplifier. A plurality of filter elements are configured in parallel, wherein each filter element receives an output from the first combiner. A second combiner combines outputs from the filter elements with the original input signal and the filter elements have mutually different filtering characteristic.

Abstract: The frame (10) comprises a seat tube (11) to the top end (11a) of which a saddle (12) is to be connected, and a front structure (14) and a rear structure (15) which are identical and have, in side view, a generally V-shaped configuration with the ends (14a, 14b; 15a, 15b) connected to the seat tube (11) and the respective vertices (14c, 15c) facing in opposite directions relative to the seat tube (11).

Abstract: The system comprises a pair of optical assemblies, left and right respectively, each including a support base on which a plurality of optical elements are mounted, and a transparent cover for protecting the optical elements and being passed through by the light emitted by these latter. Each optical element includes a LED light source controllable by a remote control unit and is intended to carry out one function from the group comprising position light, dipped-beam headlight, main-beam headlight, fog headlight and turn indicator light. By virtue of the use of LED optical elements, it is possible to provide optical assemblies of small sizes, the shape of which can be adapted easily to that of the vehicle body.
