Využití zvukové karty jako nízkofrekvenčního generátoru

Abstract

The objective of this thesis is to design and realize a programmable generator and check its properties. In its first part this thesis deals with a possible usage of a sound card as a low-frequency generator. In this part I also compare two different possibilities of the realization of the low-frequency generator using the two libraries of NAudio and CSCore. The second part of my thesis deals with the design and realization of a generator with a time-dependent course, the possibility of the setting of a course type, amplitude and the frequency of oscillation. The third part verifies the properties of the created generator by means of gauging and I compare the properties with those of a commercial generator. I also compare the results of several different classes of sound cards. The gauging was done on the devices of TDS 2012B and DYNON INSTRUMENTS ELAB-080 Spectral Analyzer, which was also used as a signal generator to compare with a software version. The last part of my thesis describes the operating of the designed and created low-frequency SIGEN generator
