Abstract

U ovom diplomskom radu projektiran je baterijski napajan odašiljač sinusnog signala u rasponu frekvencija od 100 kHz do 400 MHz namijenjen za mjerenje prijenosne karakteristike sustava za prijenos signala ljudskim tijelom. Razvijeni sustav baziran je na sklopu za direktnu digitalnu sintezu (DDS, engl. Direct digital synthesis) sinusnog signala AD9910 proizvođača Analog Devices i SMT32WB55RG mikrokontroleru proizvođača STMicroelectronics. U programskom paketu Altium Designer projektirana je dvoslojna tiskana pločica koja omogućuje programiranje, Bluetooth komunikaciju, odvojeno baterijsko napajanje te spajanje vanjskog sučelja s elektrodama i prilagodnom mrežom s generatorom signala na pločici. Omogućena su dva načina generiranja signala na izlazu generatora, kojima se upravlja programski putem Bluetooth komunikacije, prema definiranom protokolu.

Abstract (english)

In this thesis, a battery-powered sine signal generator for measurement of transfer characteristic of intrabody communication systems in frequency range between 100 kHz and 400 MHz was designed. The developed system is based on the direct digital synthesis (DDS) circuit AD9910 by Analog Devices and the SMT32WB55RG microcontroller by STMicroelectronics. Using Altium Designer PCB design software, a two-layer board was designed, enabling programming, Bluetooth communication, a battery supply, and external interface for connecting electrodes and matching network with the on-board signal generator. Two ways of signal generation are enabled and controlled via Bluetooth communication, according to a defined protocol.
