Abstract

Matematička operacija integracije moguća je izvedbom integratora, elektroničkog sklopa koji se bazira na operacijskom pojačalu u invertirajućem spoju. Rezultat integracije signala jednaka je umnošku vremenske konstante i integrala ulaznog signala u jedinici vremena. Koristeći ostale elektroničke sklopove poput punovalnog ispravljača, komparatora i logičkih funkcija, realiziran je sustav za buĎenje mikrokontrolera detektrorom srednje vrijednosti signala. Sustav je moguće unaprijediti koristeći sklopove s memorijom (bistabil) ili mikrokontroler radi mjerenja ili obrade informacija.

Abstract (english)

The mathematical operation of integration is possible with practical integrator,electronic circuit based on operation amplifier with negative feedback. The integrator output is equal to the integral of the input voltage and time constant of the integrator. With the use of other electronic circuits, such as the precision full wave rectifier, comparators and logic functions, system to wake up the microcontroller by detecting the mean value of signal is realized. System can be improved by using components with memory (bistable) or microcontroller to measure or process information.
