    摘要: A digital filter configuration for the filtration of a digital video signal, wherein the functions of a zoom filter, in the form of a low-pass filter, which is a polyphase filter, and of at least one peaking filter, in the form of a high-pass filter, are realized, wherein the functions of the two filters are realized in a combined filter (1-17) in an integrated circuit in a manner such that, for each phase of the zoom filter to be set, combined filter coefficients are calculated from filter coefficients stored for this phase of the zoom filter and from filter coefficients stored for the peaking filter, which combined filter coefficients are applied to the video data to be filtered in a filtration process, so that both filtration functions are executed with the combined filter coefficients in this filtration process.

    摘要: In one embodiment, an apparatus includes a plurality of photovoltaic units having respective pairs of first and second power terminals connected in series. Each photovoltaic unit in the series includes a bypass switch connected in parallel with the photovoltaic current source of the photovoltaic unit. The bypass switch is configured to provide a bypass of the photovoltaic current source in response to a respective switch control signal. A control circuit determines electrical characteristics of the one or more of the plurality of photovoltaic units by operating the bypass switches of one or more of the photovoltaic units in an open state and operating the bypass switches of the other ones of the photovoltaic units in a closed state. Electrical characteristics exhibited by the series connection of the plurality of photovoltaic units are measured using a detection circuit.
