    摘要: A method and apparatus for improved video bandwidth resolution in DFT-based spectrum analysis is disclosed. A first embodiment comprises an emulation of a continuous range of video bandwidths in DFT-based spectrum analysis using overlapping resolution bandwidth frames. A second embodiment utilizes frame weighting to reduce the standard deviation in the spectrum of noise signal to emulate a corresponding standard deviation of a specified video bandwidth.

    摘要: A system and methodology that can minimize disturbance during an AC operation associated with a memory, such as, program, read and/or erase, is provided. The system pre-charges all or a desired subset of the bit lines in a memory array to a specified voltage, during an AC operation to facilitate reducing AC disturbances between neighboring cells. A pre-charge voltage can be applied to all bit lines in a block in the memory array, or to bit lines associated with a selected memory cell and neighbor memory cells adjacent to the selected memory cell in the block. The system ensures that source and drain voltage levels can be set to desired levels at the same or substantially the same time, while selecting a memory cell. This can facilitate minimizing AC disturbances in the selected memory cell during the AC operation.

    摘要: A method for suppressing banding and rolling flicker in video acquired by a video camera. The method comprises acquiring a plurality of video frames and assessing an amount of rolling flicker in the plurality of video frames. The method further comprises configuring the video camera to quiet banding and rolling flicker responsive to periodic illumination at a first frequency if the amount of rolling flicker is above a threshold, and, configuring the video camera to quiet banding and rolling flicker responsive to periodic illumination at a second frequency if the amount of rolling flicker is below the threshold.
