    摘要: A processing circuit for optical data is provided. The processing circuit includes a signal-processing module and a radio frequency (RF) signal-summing module. The signal-processing module averages and filters the data signals to obtain a low-frequency signal. The RF signal-summing module receives the data signals and the low-frequency signal, sums the data signals to obtain a summed data signal, and subtracts the low-frequency signal from the summed data signal to obtain a RF summing signal.

    摘要: A method for calibrating a data processing apparatus to set a target firmware trim value is disclosed. The data processing apparatus is for converting a non-test pattern to a non-test output according to the target firmware trim value under a normal mode. The method includes: driving the data processing apparatus to convert a test pattern into a test output according to a test firmware trim value received under a calibration mode; and analyzing the test output to tune the test firmware trim value outputted to the data processing apparatus, and controlling the data processing apparatus to store a specific test firmware trim value as the target firmware trim value when an analysis result of the test output generated in reference to the specific test firmware trim value indicates that a predetermined criterion is met.
