TL;DR: In this paper, a level shift processing part 20 bit-shifts inputted 24-bit audio data to a low order by two bits and outputs 26-bit digital data Digital data of 26 bits, which are bitshifted, are equalized through an equalization processing part 22 and subjected to an over-sampling processing for four times performed by an over sampling processing part 24 Then, the resultant data are outputted to a ΣΔ modulation part 26
Abstract: PROBLEM TO BE SOLVED: To provide a data processing system which can prevent the deteriora tion of information SOLUTION: A level shift processing part 20 bit-shifts inputted 24 bit audio data to a low order by two bits and outputs 26 bit digital data Digital data of 26 bits, which are bit-shifted, are equalized through an equalization processing part 22 and subjected to an over-sampling processing for four times performed by an over-sampling processing part 24 Then, the resultant data are outputted to a ΣΔ modulation part 26 The ΣΔ modulation part 26 performs a ΣΔ modulation processing on digital data, which are over-sampled to generate 24 bit digital data of 24

TL;DR: A network force balanced accelerometer (NFBA) with multiple interfaces was designed in this paper and has many good specifications, low cross sensitivity in full bandwidth, low power consumption, low volume, 26 bit effective resolution.
Abstract: A network force balanced accelerometer (NFBA) with multiple interfaces was designed in this paper. One integrated and orthogonal three-component mechanical base was used in the NFBA. One record circuit with high precision analog-to-digital convertors and low-power ARM STM32F407 was embedded in the force balanced accelerometer. The record circuit was used to do high precision and high speed analog-to-digital conversion, data management and communication. In the record circuit, one group of logic signals drives three ADS1282. That synchronously generates three channel 32 bit resolution digital vibration data. ARM STM32F407 with a 4-core 1.4G∗4 CPU and multiple interfaces was selected to manage clocks, process data, communicating. Five types of linearity power supply chip were selected to design high-precision powers in the NFBA. Every type of power supply was isolated designed. Each channel's power supply was independently designed. Then the effective resolution of analog-to-digital conversion can achieve 26 bit in the record circuit. The NFBA designed in this paper has many good specifications, low cross sensitivity in full bandwidth, low power consumption, low volume, 26 bit effective resolution. It supports 1000Hz sample rate, serial interface, cable network and so on.
