Discrete convolution calculator online

Compute full discrete convolution between two numeric sequences. Use this for the specific transformation described above. Start with the fixed sample and compare its result before replacing it with your own representative input.

How to use it

Paste JSON matching the structure in the example. Supply kernel sequence in the second input. Choose Calculate. Review the output, then copy or download it.

Worked examples

Use this for the specific transformation described above. Start with the fixed sample and compare its result before replacing it with your own representative input.

Reproducible worked example

Settings: No additional settings.

Input:

[1,2,3]

Kernel sequence:
[1,1]

With the input and settings above, the tool produces:

Output:

[
  1,
  3,
  5,
  3
]

The example returns 4 top-level items in an array.

Limitations and common mistakes

Calculations use your supplied assumptions and floating-point arithmetic. Check input order, units and the worked example before relying on a result.
Combined input is bounded to 150,000 characters; output text is bounded to 1.2 million characters. Some algorithms impose smaller limits, stated in their error messages.
Both inputs must follow their own documented format. Changing direction or mode can require different input; the example is for the displayed settings.

Frequently asked questions

What format should I enter?

Paste JSON matching the structure in the example. The second input is kernel sequence. The worked example shows the supported structure and actual output.

How can I calculate full discrete convolution between two numeric sequences online?

Paste JSON matching the structure in the example. Supply kernel sequence in the second input. Choose Calculate. Review the output, then copy or download it.

Where is my input processed?

The bundled tool processes input in your browser. It does not upload tool input to a conversion service. Other site plugins, analytics, advertising and browser extensions may have separate behavior.
