Abstract
Ovaj rad bavi se implementacijom generatora signala izvedenog ispreplitanjem digitalno analognih pretvornika na mikrokontroleru iz porodice PSoC 5LP. Implementacija sustava s vremenski isprepletenim digitalno analognim pretvornicima povećava efektivnu frekvenciju uzorkovanju, što omogućuje sintezu signala viših frekvencija i šireg frekvencijskog područja. Namjena sustava je generiranje signala nosioca za prijenos signala ljudskim tijelom te je stoga naglasak rada stavljen upravo na generiranje signala sinusnog valnog oblika. Generator signala implementiran je na razvojnom sustavu koristeći interne komponente i vanjski otpornik, koji čini stupanj pretvorbe struje u napon kako bi se generirani signal mogao promatrati osciloskopom. Karakteristike generatora signala izvedenog ispreplitanjem digitalno analognih pretvornika u skladu su s teorijskom pozadinom te ponajviše ovise o vremenskoj usklađenosti rada digitalno analognih pretvornika, koja je lošija što je frekvencije uzorkovanja viša. Signal sinusnog valnog oblika frekvencije reda veličine megaherca uspješno je generiran, uz maksimalnu frekvenciju generiranog signala od 10 MHz. Neželjene spektralne komponente najviše snage predstavljaju harmonici osnovnog signala te ih je potrebno filtrirati kako bi se smanjilo harmoničko izobličenje signala.
Abstract (english)
The topic of this thesis is an implementation of a signal generator using time interleaved digital to analog converters on a PSoC 5LP microcontroller. Implementation of a system with time interleaved digital to analog converters increases the effective sampling rate, which enables the synthesis of higher frequency and higher bandwidth signals. This system is intended to be used for carrier signal generation in an intrabody communication network, so the emphasis of this thesis was put on sinusoidal signal generation. The signal generator was implemented on the development kit using internal components and an external resistor, which converts output current to voltage so that the generated signal can be observed with an oscilloscope. The characteristics of the interleaved signal generator are in line with the theoretical background and mostly depend on the timing of the operation of digital to analog converters, with timing mismatch increasing with the sampling rate. A sinusoidal signal in the megahertz frequency range has been successfully generated, with a maximum frequency of 10 MHz. Spurious spectral components of the highest power are the harmonics of the base signal and need to be filtered out to reduce the harmonic distortion of the signal.
