In this thesis, after reviewing the research conducted in the field of implementing data acquisition systems, first, the appropriate equipment for the project was selec‎ted, an‎d then the method of signal extraction from the sensor an‎d its preparation for entry into the analog-to-digital converter was addressed. These include the design of printed circuit boards for voltage an‎d current transducers, an‎d the design of a two-stage filter to eliminate noise an‎d neutralize the skin effect of the signal. Subsequently, to ensure the correct operation of the fabricated boards, the results of the designed circuits were first extracted using a data acquisition card an‎d compared with the results of a voltage an‎d current measurement device. After ensuring the proper functioning of the transducer boards an‎d filter boards, a data acquisition system based on data acquisition cards was designed an‎d implemented. Then, the data acquisition cards were replaced with a condition monitoring an‎d data acquisition board. The designed condition monitoring an‎d data acquisition board, in addition to simultaneous sampling of 10 channels, features a higher sampling rate an‎d SDCARD connectivity to eliminate the need for a computer during data acquisition. Furthermore, it supports numerous communication protocols for establishing connections with various PLCs, computers, an‎d other industrial equipment.
