3.27 Sound/LAN/Modem Test Program
Subtest 02 Sign Wave
This subtest is executed by loading the COM file (ADSIN.COM). The program
expands sign wave data table from 16KB to 64KB, and creates the play data. Then
it transfers the data between the DMA and the CODEC to play the sign wave. (It
sounds like a continuous beep). By using wave measuring devices such as an
oscilloscope, the data can be measured as a sign wave.
When the subtest is executed, the following message appears.
[Sign wave test !]
Sign wave is expanded from 16KB to 64KB data and is played.
NOTE: The menu displayed by your computer may be slightly different from the one
shown above.
