Frequently Asked Questions

Find Quick Answers

What signal formats are supported?

The tool supports sine waves, square waves, triangular waves, and custom signals. Custom signals can be uploaded as CSV files or entered as comma-separated values.

What analysis features are included?

The analyzer performs Fast Fourier Transform (FFT) for frequency spectrum analysis, calculates amplitude statistics (mean, RMS, peak-to-peak), visualizes waveforms, and identifies dominant frequencies.

Is there a file size limit for uploads?

The tool processes signals client-side, so file size is limited by browser memory. For optimal performance, keep signals under 1 million data points.

Can I analyze real-time signals?

This tool analyzes static signal data. For real-time analysis, you would need to capture signal data and upload it periodically.
