Abstract: Apparatus for controlling the generation of a DC signal at the output of a mixer, so that the DC signal is predictable, enabling a static offset compensation voltage to offset the DC signal. The apparatus comprises a mixer configured to receive a first and a second input signal, the mixer being such as to generate a first DC signal at the output of the mixer when the first and second input signal have the same frequency and a first relative phase, a phase detector for determining the relative phase of the first and second signals, and a phase modifier configured to modify the phase of the second signal relative to the first signal in dependence on the determination of the relative phase between the first and second signals such that the resulting DC signal at the output of the mixer is the first DC signal.

Abstract: Method and peripheral device to facilitate the installation of software on a host device to allow communication between that host device and a peripheral device. On connection to a host device a peripheral device presents in a first mode. In the first mode the device identifies itself as a Human Interaction Device and transmits information to the host device to facilitate the installation of the software. Subsequently the peripheral device operates in a second mode in which it identifies itself according to its real function.

Abstract: The present invention is directed to a phase shifting arrangement for generating a set of mutually orthogonal signals. In one aspect, the invention provides a system that includes a phase shifting unit for receiving an input signal. The phase shifting unit includes a first phase shift circuit for generating a first output signal phase-shifted by a first amount with respect to the input signal, a second phase shift circuit for generating a second output signal phase-shifted by a second amount with respect to the input signal, and a third phase shift circuit for generating a third output signal phase-shifted by a third amount with respect to the input signal.
