Měření přenosových vlastností reproduktorových systémů

Abstract

This thesis deals with the analysis of chosen methods for determining frequency response of loudspeaker systems followed by software development used to processing of measured signals. In the introduction, physical laws regarding propagation of the sound and essential features of speakers are described which makes key prerequisites for understanding the basic principles behind this field. Thereafter thorough analysis of particular techniques for identification of transmission characteristics is made and on the base of the comparison of these techniques optimal method is chosen. Subsequently, the best method is implemented into the virtual instrumentation in LabVIEW which will be alternative to commercial applications which are available for this purpose. Finally, created application is debugged through NI's measuring modules and it is included on the attached CD.
