Abstract:

Analog telecommunication system equipment is now starting to develop and be replaced with digital telecommunication systems, one of them is in the audio signal processing. The focus of audio processing is audio crossover. Audio crossover in development there are still many who use analog systems.

Abstract:

This article presents methods of digital systems processing data from various sensors or sources, synchronization system and algorithm based on the program developed for data processing in the system. Methods of high-speed data processing in systems with multi-channel analog and digital sensors are analyzed. In a digital system, it has been investigated whether data from multi-channel sensors can be delayed in time t or cause errors in calculation due to the time taken for measurement. In order to eliminate the errors of data obtained from multichannel sensors, a method and model of synchronou

Abstract:

This paper mainly introduces a FPGA-based data acquisition system which is designed to acquire multi-channel analog signal and one channel digital signal. Analog data and digital data are stored into a FLASH memory in a mixed frame format. When the acquisition finished, the data in the FLASH was read out via the LVDS communication interface to a data-read device, and the host computer receives the data through the USB bus, so the subsequent data processing and analysis can be accomplished and the information we needed can be got. The design is applied successfully to a remote measurement syste
