Wavelet Transform Calculator

Wavelet Transform Calculator: Wavelet Transform Calculator performs a Discrete Wavelet Transform (DWT) on a 1D signal using Haar wavelet. Enter signal, click Calculate to get coefficients.

How to Use:

1. Enter a signal as comma-separated numbers (e.g., 1,2,3,4).
2. Click “Calculate” to compute the Haar Discrete Wavelet Transform.
3. Use “Copy Result” to copy the output.

Calculation Details:

• Transform: Single-level Haar DWT.
• Outputs: Approximation (cA) and detail (cD) coefficients.
• Method: Averages and differences of pairs (normalized by √2).

Important Notes:

• Signal length must be even for Haar DWT.
• Enter valid numbers (e.g., integers or decimals).
• Clipboard access requires HTTPS.
