Abstract:
1. A device for applying a scaling factor to a horizontal scan of a scanner comprising: a switching device having a first input terminal and a second input terminal, said switching device receiving at said first input terminal thereof an input signal including a number of bits, said switching device having an output terminal producing thereat a signal selected from said input signal and a second signal responsive to a first clock cycle number; an addition device having a first input terminal and a second input terminal and operable to produce at an output terminal thereof a sum of a signal provided to said first input terminal and a signal provided to said second input terminal, said output terminal coupled to said second input terminal of said switching device and providing thereto said second signal; a shifting device having an input terminal coupled to said output terminal of said switching device and having an output terminal coupled to said second input terminal of said addition device, said shifting device being operable to produce at said output terminal thereof said selected signal shifted a number of bits corresponding to a clock cycle number; and an output terminal coupled to said output terminal of said shifting device and providing thereat an output signal upon a second clock cycle number.
