The apparatus with a controllable transmission function circuit by a command signal and approximation methods

摘要

Apparatus (20) comprises a circuit (26) which delivers a signal of the output (out) in response to an input signal (in), means (c) in order to change the values (r) of said response with at least one control signal (v), the computing means (24) in order to determine the second pairs (ra, va), response values / control signal values, starting from a first approximation of pairs (r1, v1) (r6, v6), response values / control signal values from the circuit (26). The apparatus comprises: & br / - of the coding means (22) in order to determine at least one linear regression function (d) forming an approximation of a series of said first pairs (r1, v1) (r6, v6) and to determine the codes specific to said function, & br / - the calculation means (24), on the basis of said specific codes, a transcoding of predetermined values (req) of response in the control signal values belonging to said second pairs. & br / & the coding means (22) may also be arranged on the outside of the apparatus (20). br / application to the adjustments of equipment such as television radio receiver, video recorder or the like. & br / application: television radio receiver, a tape recorder.
