Real time digital correction for distortion in photoelectronical measuring system;

Circuit techniques used to achieve this level of power dissipation include clock generation and digital correction.

One of the important technology of infrared imager is nonuniformity correction, The algorithm of nonuniformity digital correction based on the imaging feature of SPRITE infrared imager was presented.

Research and Design of Two-step Pipelined Analog to Digital Converter Based on Digital Calibration;

This paper focuses on the amplitude and phase difference among channels of dual- channel receiver, and presents a digital calibration scheme based on DSP.

A method of digital calibration in the amplitude and phase imbalances of sum and difference channels, and of angle error normalization processing is provided.

The paper analyses the cause of anomalous stretch of normal moveout in seismic data processing and the characteristics digital normal moveout correction.
