IPC: H03M1/12
Filed: 2012-01-25
Abstract: PROBLEM TO BE SOLVED: To enable confirmation of all data obtained by a plurality of ADCs different in a gain to thereby achieve reduction in a memory capacity for storing data while easiness of debugging hardware is secured.SOLUTION: The data collection device multiplies data obtained by an ADC 3b on a low gain side by a constant equivalent to a gain difference to calculate a difference between the data obtained thereby and data obtained by an ADC 3a on a high gain side with a differentiator 42, and stores the difference data and the data on the low gain side in a memory 5. On data transmission, by multiplying the data on the low gain side read from the memory 5 by the constant to calculate a difference between the data on the low gain side and the difference data with a differentiator 44, the data on the high gain side is restored. A data selector 45 selects and outputs the data when the data on the high gain side is not saturated, and selects and outputs the data on the low gain side when it is saturated. Since a bit width of the difference data is smaller than that of original data, the memory capacity can be saved, and data of both of the high and low gains can be obtained, so that it is also easy to debug the hardware.
