Recommended for High School through College.
In this exercise, you will create a simple program using the Analog Express VI and the Spectral Measurements Express VI to continuously collect microphone data and continuously perform an FFT analysis on the data. A Fast Fourier Transform (FFT) is a mathematical algorithm commonly used in digital signal processing to determine the dominant frequencies in a complex waveform.
In this experiment, you will
- Create a LabVIEW VI to continuously collect and analyze data.
- Incorporate LabVIEW Express Analysis functions.
- Use a While Loop to keep collecting and analyzing data until stopped by the user.
