Abstract
This work presents a real time system of acquisition, monitoring and signal processing based on the synergy of hardware and software. In the stage of signal acquisition, a circuit board was built. This circuit board acquires two signals, one from a phototransistor sensor and other one from an ultrasonic sensor. The sending and processing of the data was through the Arduino platform. A graphical user interface (GUI) using Matlab® was implemented for the stages of monitoring and processing. For these stages two interfaces were designed and implemented with the aim of show the signals of two forms, continuous and digital, and their processing. For the processing stage, several operations such as convolution, median filter and the Fast Fourier Transform were applied to the signal. On the other hand, another aim of the implementation of this system was with the purpose to obtain a didactic tool to complement and support learning in the area of signal processing and thus generate a bigger interest and motivation of the students to practice the knowledge acquired in classes.
