Funkční generátor signálů s obvody pro přímou digitalní syntézu

Abstract

This thesis deals with signal generation, especially focus on the possibility of using direct digital synthesis method. The aim of this work is to propose and construct function generator, which will be available to students in the lab either to closer acquaintance with this method of signal generation or as a laboratory device. Realized facility will allow simple digital signal modulation. The user can operate this device in two ways, via the user interface in the PC through the USB bus or using the display and keypad located directly on the product. Furthermore, this work deals with methods of measurement signal distortion and the self measurement in frequency and time domain.
