Data Acquisition & Processing, Signal & Image Processing

Data acquisition (DAQ) is the process of measuring a physical or electrical parameter such as voltage, current, temperature, pressure, sound or humidity using a computer. DAQ systems consist of sensors, DAQ measurement hardware, signal conditioning circuitry, analog-to-digital converters, and some kind of a computer with programmable software. There are cases in which data isn’t readily available or complementary data is required. Depending on the situation, sometimes mere sampling might be enough or an automated data acquisition system may be required. Our engineers will assess your case and define the type and complexity of sampling activities; and accordingly design & develop any data acquisition systems that could be needed to retrieve data from systems or processes. For data acquisition applications we usually deploy software programs developed by major suppliers such as National Instruments (NI) developed using general purpose programming languages such as Assembly BASICCC++C#FortranJavaLabVIEWPascal, etc.  as well as stand-alone data acquisition systems called data loggers. Depending on client needs, our engineers modify or custom develop data acquisition programs. Collected data is in most cases not ready for use. It must be inspected, filtered, transformed, validated and then used. Once ready, we can work from simple tasks such as sorting, summarizing, classifying and reporting; to complex analysis using statistics, data mining, descriptive and predictive modeling, visualization, among others. Depending on the project, we assign subject expert engineers and mathematicians to establish a custom tailored data acquisition and processing system for our clients. 

Signal processing is considered as an enabling technology that encompasses the fundamental theory, applications, algorithms, and implementations of processing or transferring information contained in many different physical, symbolic, or abstract formats broadly designated as signals. Some application fields of signal processing in engineering are audio and digital signal processing, image processing, speech signal processing & speech recognition & noise reduction & echo cancellation, video processing, waveform generations, demodulation, filtering, equalization in wireless communication, audio & video & image compression.
