How to Create a Power Spectral Density Plot
- 1
Upload Your Signal Data
Begin by uploading your time-series data. This should be a file containing your signal measurements, like a CSV or TXT file.
- 2
Describe Your Desired Plot Style
In the text box, explain how you want your plot to look. Specify things like 'use a logarithmic frequency scale' or 'make the plot line green'.
- 3
Generate PSD Plot
Click the generate button. Our AI will process your data, calculate the Power Spectral Density, and apply the custom styles you described.

Download Your Plot
Your high-resolution PSD plot is ready to download. Save the watermark-free PNG file for use in your research, reports, or projects.
Instant Frequency Domain Insights
Move from raw time-series data to a clear frequency-domain view without writing a single line of code. A Power Spectral Density (PSD) plot shows how the power of a signal is distributed over different frequencies. Our tool lets you upload your data file, and it instantly calculates and visualizes the PSD for you. This is perfect for identifying dominant frequencies, analyzing random signals, or characterizing broadband noise in your data. Get immediate insights into the spectral characteristics of your signals with just a few clicks.

Customize Your Plot with Simple Text
Take control of your plot's appearance using conversational language. After uploading your signal data, describe how you want the plot to look. You can specify details like axis labels, colors for the plot lines, titles, and whether to use a logarithmic or linear scale for the frequency or power axes. This unique AI-powered feature allows you to tailor the visualization to your specific presentation or analysis needs, creating professional-grade charts that are easy to interpret and share with others in your field.

Frequently Asked Questions
A Power Spectral Density (PSD) plot is a tool used in signal processing that shows how the power of a signal is distributed across a range of frequencies. It helps you see which frequencies are strong and which are weak, providing a frequency-domain view of the signal instead of a time-domain one.
The x-axis of a PSD plot represents frequency, and the y-axis represents power density (e.g., V²/Hz). Peaks on the plot indicate frequencies where a significant amount of the signal's power is concentrated. A broad peak suggests power is spread over a range of frequencies, while a narrow, sharp peak points to a specific, dominant frequency.
Our tool is designed to work with standard time-series data formats, such as a single-column CSV or TXT file where each row represents a signal amplitude measurement at a uniform time interval. Ensure your file contains the raw signal data you wish to analyze.
A Fourier Transform decomposes a signal into its constituent frequencies and their amplitudes. A PSD plot takes this a step further by showing the distribution of power (which is related to the square of the amplitude) per unit of frequency. PSD is particularly useful for analyzing random or noisy signals.
Yes. You can request a logarithmic scale for either the frequency (x-axis) or the power (y-axis) using a simple text prompt. For example, you could type 'plot with a log scale on the frequency axis and a linear scale on the power axis' to customize your output.
The units of a PSD plot are typically power per unit of frequency. For example, if your input signal is in Volts, the PSD will have units of Volts squared per Hertz (V²/Hz). The tool automatically handles the calculation based on your input data.
