  • Patent number: 7796967
    Abstract: An object of the present invention is to provide a noise removal apparatus, of a simplified configuration, capable of removing a noise. A band separation section 351 separates an inputted digital signal into a digital signal D1 and a digital signal D2 by using, as a boundary, the center frequency of a frequency band of the inputted digital signal. The phase adjustment section 352 adjusts a level and a frequency band of the digital signal D2, and outputs, as a removal signal R, a signal for which the level and the frequency band have been adjusted. The adder 353 adds the removal signal R to the digital signal D1, thereby enabling a signal obtained by removing an in-vehicle noise from the digital signal D1 to be outputted as a corrected signal A.

  • Publication number: 20090269167
    Abstract: A current processing mode is judged. The current processing mode can be a first mode, in which both a punching process and a binding process are performed, and a second mode, in which only the punching process is performed. A paper unit spacing, which is an interval between a last sheet of paper in a preceding paper unit and a first sheet of paper in a subsequent paper unit, is set depending on the current processing mode. A paper unit spacing for the first mode is longer than a paper unit spacing for the second mode.
