Part I †- Advanced Examples
- Open Spectrum Analyzer.vi (click
to download). Set the Frequency 2 and 3 to zero. Also change
Amplitude 2 and 3 equal to zero. Change the Frequency bar and listen to
the signal from the speaker. Pay attention to the signalís frequency as it
is a very good LabVIEW program to measure Fourier
transform of various input signals.
Part II - Practice
- Open Dice.vi This VI shows how you can generate a random
number between 1 to 6. Note how this program is put together.
the Ding.vi program. Understand how it operates.
Then change this program such that you can change the TONE and its
DURATION from the front panel. Hiont: You should use knobs. Show your VI
to the instructor.
In a NEW vi use this module as a sub-vi. Use a knob to modify the
frequency and a selector to change the signal type. Show your VI to the
the Signal_monitor.vi. Change the Square waveform
to Sine waveform. Also, add an indicator such that you can monitor the
frequency of the signal you are generating.
Part III - More Examples
are some more examples you can do on
your own to learn more about LabVIEW.
