Abstract
U ovome završnom radu obrađeno je modeliranje, dizajn i implementacija pametnog senzorskog sučelja niske potrošnje za detekciju i klasifikaciju zvučnih signala. Sučelje je modelirano idealnim elementima i svaki je funkcijski blok kruga definiran svojim jednadžbama. Zatim je sklop simuliran korištenjem SPICE alata te je napravljena implementacija na tiskanoj pločici. Na MSP430 mikrokontroleru programiran je konačni automat koji upravlja vremensko-frekvencijskom analizom signala spojenog na senzorsko sučelje. Izmjerene su i diskutirane vrijednosti osjetljivosti, specifičnosti, preciznosti, točnosti i potrošnje sklopa u ovisnosti o različitim ulaznim signalima
Abstract (english)
This Bachelor's thesis deals with modelling, design and implementation of a low power smart sensor interface for detection and classification of acoustic signals. The interface is modelled with ideal elements and each building block is given a set of it's defining equations. Then, a SPICE simulation and PCB implementation using low power elements is given to measure the performance of the design. An MSP430 microcontroller is programmed using state machines to conduct a sequential spectrotemporal analysis of an acoustic signal using the designed sensor interface. Sensitivity, specificity, precision, accuracy and current consumption are measured and results are discussed in respect to the different input signals
