Abstract

Ugradbeni sustavi niske potrošnje važni su u današnjoj tehnologiji. Detektor duljine trajanja razine signala je upravo jedan takav ugradbeni uređaj. U okviru ovoga rada dizajniran je i ispitan jedan takav uređaj. Uređaj radi na način da najprije prima ulazni signal koji nakon toga prolazi kroz detekciju ovojnice. Zatim tu ovojnicu uspoređujemo s nekom vrijednosti i generiramo impuls koji traje sve dok je vrijednost ovojnice veća od referentne vrijednosti. Taj impuls uspoređujemo s unaprijed određenim vremenskim prozorom i ukoliko je impuls trajao dulje od toga vremenskoga prozora generiramo novi impuls koji pobuđuje mikrokontroler MSP430G2231 iz stanja niske potrošnje.

Abstract (english)

Low power embedded systems are really important in today's technology. Signal peak-value-duration detector is one example of the low power embedded device. That device is designed and simulated within this thesis This device first takes an input signal then that signal goes through peak detection. Then we compare that envelope with some reference signal. Then we generate one impuls that lasts as long as the value of the envelope is grater than value of the reference signal. Duration of that impuls we compare with the known duration of some other signal and if the duration of the impuls is longer than duration of the signal we generate another impuls that wakes up microprocessor.
