To launch labAlive simulation applications you need a Java Runtime Environment supporting Java Web Start on your system. Here you can get more information about installing the right Java version.
Instruction Manual (German)
Explore how frequency modulation varies the frequency depending on the source signal.
Start
Vary the DC signal value and listen how the frequency of the modulated signal changes.
Change waveform
Change the waveform of the signal generator and produce different siren sounds.
Modulate speech and music
Now select speech and music source signals. Can you understand the frequency modulated speech?
Vary the modulating signal's amplitude and thus also the frequency deviation. What is the impact on the speech intelligibility?
