Education methods for testing of Analogue to Digital (A/D) converters in laboratory exercises at the Czech University of Life Sciences Prague, Faculty of Engineering, Department of Electrical Engineering and Automation are stated in the paper. A/D converters are inseparable parts of significant quantity of sensors and actuators used in agriculture machinery. Short introduction to the background and principles of A/D converters and to their parameters are presented. Next part of the article deals with a description of the test methods in time and frequency domain. The used methods are the histogram test and the best sine wave fit method in time domain and frequency analyses using Discrete Fourier Transformation in frequency domain. The measured parameters are Effective Number of Bits (ENOB), Signal-to-Noise Ratio (SNR), Signal-to-Noise And Distortion (SINAD), Effective Resolution (ER), Total Harmonic Distortion (THD) and Spurious-Free Dynamic Range (SFDR). The following part contains an implementation of the proposed algorithms in LabVIEW graphical programming language. Finally, the created program for education of testing A/D converters and its principles is described and the results of the methods are discussed. [ABSTRACT FROM AUTHOR]
