Information Processing Laboratory Exercises

Use of the LabView program, steps of the development of virtual instruments. Simple exercises: timing, signal generation, displaying. Implementation of a virtual instrument (chosen from a list). Possible instruments: function generator, spectrum analyzer, oscilloscope, equalizer. The development is supported by built-in functions.

Learning of the VI set given by the hardware, steps of the development of a new project. Simple exercises: thermometer, reaction time meter. Implementation of an embedded system (chosen from a list). Possible systems: temperature control, remote control of a toy-car, sensor network for data acquisition. The development is supported by built-in functions.

Implementation of the LMS algorithm. Versions of the LMS algorithm, the XLMS algorithm. Investigation of adaptive transversal (FIR) filters. Identification by the LMS algorithm. Adaptive echo cancelation in electronic and acoustic systems.

Implementation of a classification system by multi-level processing. Processing of vibration and sound signals: extraction of the main parameters by time domain and frequency domain methods, classification by neural and fuzzy systems. Investigation of parameter setting and learning of neural networks. Investigation of parameter setting of fuzzy systems. Musical sound recognition by neural and fuzzy systems.

Signal transmission on radio channel. Implementation of synchronization of sampling. Use of interpolation techniques. Sampling of acoustic signals by “mitmót”, fusion on DSP. Better exploitation of the bandwidth: compression techniques. Influence of the number of the sensors (the number of the sensors is equal or greater than or less than required). Feedback in sensor networks.
