Electrical Computers: Arithmetic Processing And Calculating > Electrical Digital Calculating Computer > Particular Function Performed > Interpolation/extrapolation Interpolation/extrapolationInterpolation/extrapolation patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.10/05/06 - 20060224649 - Interpolation and decimation using newton polyphase filters An interpolation filter for interpolating a digital signal includes a cascade of template filters, each having an identical template transfer function A(z), which is arranged to receive and filter an input sequence representing the digital signal sampled at an input sampling rate. Ancillary circuitry is coupled to the cascade so ... 02/23/06 - 20060041609 - System and method for multi-dimensional lookup table interpolation A technique for using a one or two dimensional table lookup to provide the appropriate index and fraction for a second lookup table. The second lookup table can be a multi-dimensional lookup table. The one or two dimensional lookup table allows nonlinear conversion between input values and output values obtained ... 01/19/06 - 20060015548 - Interpolation of video and audio digital data In the process of interpolation of video and/or audio digital data Sn, an interpolated value is chosen depending on whether or not an edge is detected. The edge detection is performed as follows. Let L=|S2n−S2n−2|, C=|S2n+2−S2n|, and R=|S2n+4−S2n+2|. An edge is detected when R>9(C+L) or L>9(C+R). A predictor P2n+1=K1S2n+K2S2n+2 provides ... 01/12/06 - 20060010185 - Digital signal decimation by subspace projection A digital signal, x(n) (where n is an integer), is decimated by determining a signal vector, y(k), of size M by partitioning samples of the digital signal, x(n) according to sampling phases of the samples. The signal vector, y(k), is projected onto an N-dimensional sub-space, wherein N is an integer ... 11/03/05 - 20050246403 - Interpolation method and apparatus performing the same An interpolation method and an apparatus are provided for determining an m-th interpolated value, Vm, between a lower boundary, LB, and an upper boundary, UB, with N interpolated intervals. The method includes the following steps (a) calculating a difference value, D, between LB and UB; (b) selecting an integer, Int, ... 09/15/05 - 20050203980 - Computing transcendental functions using single instruction multiple data (simd) operations In one embodiment, the present invention includes a method for reducing an input argument x of a function to a range reduced value r according to a first reduction sequence, approximating a polynomial for a corresponding function of r having a dominant portion f(A)+σr, and obtaining a result for the ... 06/09/05 - 20050125472 - Methods and apparatus for performing calculations using reduced-width data Methods, apparatus, and articles of manufacture for performing calculations using reduced-width data are disclosed. In particular, an example method determines reduced-width data values associated with generating and evaluating functions. Some of the reduced-width data values are stored within instructions in an instruction memory during a compile phase and retrieved from ... 06/02/05 - 20050120066 - Interpolator, interpolation method, and signal processing circuit An interpolator interpolates a digital signal obtained by digitally sampling an analog signal. The interpolator comprises a register which receives the digital signal at a plurality of taps and generates tap outputs from a plurality of the taps, a multiplier which multiplies each of the tap outputs by a coefficient ... ### FreshPatents.com Support |
