Testing Device For Optical Transfer Of The Sound
MetadataShow full item record
This paper deals with the design of an audio tester, focused on the conversion from an analogue signal to the digital signal going through Toslink cable. My design use ARM microcontroller, which generates the harmonic audio signal. This signal will go through a connected AD converter. The circuit receives this signal and microcontroller do FFT analysis. After testing frequencies among 20Hz and 20.000Hz, microcontroller puts all results of FFT analysis to one plot, represented by points. These points are sent by serial line to the computer.
