Abstract
A device is presented for processing digital signals conveyed between a common port and many particular ports. The device includes a linear processing module. The module includes filters, which simultaneously apply a phase-shift and a chosen amplitude emphasis at each of the particular ports. The phase-shift is specific to each particular port, and the amplitude emphasis is substantially the same for all the particular ports. At the common port, the device also includes a common inversion filter, which performs inverse amplitude emphasis to the chosen amplitude emphasis.
