The modulation and demodulation measurement transducers, also known as modulators and demodulators, are used in measurement devices in case of transmission of measurement information in the form of data for the results from the measurement process or exchanging control commands between controllers, intelligent sensors and measurement devices, which have computer interface. That group of devices contains also the analogue amplitude and pulse-amplitude modulators and demodulators. In this paper are proposed simulation models of amplitude and pulse-amplitude modulators and demodulators, based on mathematical models related to the operation of this type of measurement transducers and by using the computing capabilities of the Matlab software and Simulink in particular. Such modulators and demodulators simulations model can successfully be used in the training of PhD students and students for the purpose of research, analysis and visualising characteristics of the measurement transducers.
