Anil Sawe has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Sampling rate conversion using digital differential analyzers
    Patent number: 6356315
    Abstract: Magnification/reduction is achieved by a single FIR filter under the control of a Digital Differential Analyzer (DDA) as would be used to simulate a perfectly straight line on a two-dimensional raster. The single FIR filter combines the processes of interpolation, filter, and decimation. The DDA is programmed with the desired magnification/reduction ratio and provides signals that control shifting of input samples into the FIR filter and selection of FIR coefficients for the FIR filter.
    Type: Grant
    Filed: October 1, 1998
    Date of Patent: March 12, 2002
    Assignee: Oak Technology, Inc.
