Abstract:
This paper describes a variant of sinusoidal and impulse generator, built on the bases of a direct digital synthezer. Usage of such kind of generator for testing and researches is of frequent occurrence. There are strong requirements to this generator, which are difficult to be implemented in a single device. Usually the variation in its basic parameters i.e. frequency and output amplitude, have to be done in rather wide limits with a minimal step. Due to these requirements, the schemes are very complicated and a generator has limited characteristics. The direct digital synthezers (DDS), give the possibility to create a generator with output frequency, varying from mHz to GHz wit a constant step of change - mHz. In this paper is demonstrated a variant of generator, on the bases of DDS architecture, controlled by microcontroller connected with personal computer.
