Convolution Calculator

The Convolution Calculator allows users to determine the output length, required padding, computational complexity, and memory requirement for different types of convolutions given specific signal and kernel lengths, along with selected convolution and padding types.

How to Use the Convolution Calculator

This guide will help you navigate through the Convolution Calculator’s interface and understand how to use it effectively for your convolution calculations. Follow these steps to input your data and understand the results.

Step 1: Input the Signal Length

Begin by entering the signal length into the designated field. The signal length must be a number between 2 and 100. Ensure that you enter an integer within this range to meet the validation requirements.

Step 2: Input the Kernel Length

Next, input the kernel length. Similar to the signal length, the kernel length must also be a number between 2 and 100. This validation will ensure that the calculations are performed accurately.

Step 3: Select the Convolution Type

Choose the type of convolution you want to perform from the dropdown menu. You have three options:

  • Full Convolution: This will provide the full convolution output which is larger than the input.
  • Same Size Output: This outputs a result with the same length as the signal.
  • Valid Convolution: This provides only those parts of the convolution that are calculated without the zero-padded edges.

Step 4: Choose the Padding Type

Select the type of padding you want to use from the padding options:

  • Zero Padding: Pads the signal with zeros.
  • Mirror Padding: Uses a mirrored version of the signal as padding.
  • Circular Padding: Treats the signal as if it were circular, thereby wrapping around.

Ensure that you select the padding type that suits your convolution requirements and the matching criteria needed for your application.

Step 5: Review the Results

Once you have completed the input fields, examine the output fields to understand the convolution results:

  • Output Length: This field shows the length of the output signal determined by the convolution type selected.
  • Required Padding: The amount of padding required based on your selections. This is crucial for implementing the type of padding in practice.
  • Computational Complexity: Displays the estimated computational complexity. This helps in understanding the resources needed for the convolution.
  • Memory Requirement: Provides an estimate of the memory in bytes required to store the output signal.

Utilize these outputs to better plan your convolution tasks and resources.
