Latest Patents

Easley holds a patent for a technology titled "Reciprocal index lookup for BTSC compatible coefficients." This innovative algorithm calculates spectral compression and expansion filter coefficients using a value proportional to the reciprocal of a feedback/feedforward signal. The coefficients are stored in a lookup table, which is indexed by a pre-selected set of coefficient bits to generate a filter coefficient function. The first portion of the lookup table contains discrete values at index points of a line segment that corresponds to a filter coefficient function approximation. This allows for the generation of an initial discrete value corresponding to the filter coefficient function at a value of the high order bits. The second portion of the table stores slope values that indicate the slope of the filter coefficient function. A linear circuit is then used to interpolate and decimate an approximation of the compression and expansion filter coefficient function based on the slope value, the initial discrete value, and a preselected set of low order bits of the reciprocal value.
