ABSTRACT:
Current switching apparatus including at least one current switching tree comprised of cascaded sets of switching circuits, with an input set operable with sampling clock pulses supplied at a fixed frequency and the remaining cascaded sets operable at different frequencies, and further including a sample skipping circuit interconnected between successive sets for reducing the effective sampling frequency of the switching tree while maintaining the fixed frequency at which the input set operates. The sample skipping circuit includes a dump circuit selectively energized to dump selected samples produced by the input set. When the apparatus is formed of plural switching trees of different phases, a sampling clock generator having an adjustable delay circuit is used to delay sampling clock pulses by adjustable amounts so as to establish predetermined phases of sampling clock pulses of the same frequency and different phases for use in each switching tree.
