Summary

Converts a frequency-domain signal into a time-domain signal using the inverse Fast Fourier Transform (IFFT).

Description

The Inverse Complex Fast Fourier (IFFT) component reconstructs the original time-domain signal from its complex frequency components. This is useful for signal processing tasks where a frequency-domain signal needs to be converted back to time-domain.

Properties

  • Enabled – Enables or disables the IFFT calculation.
  • Order – IFFT order (default: 5), higher order gives finer reconstruction accuracy.

Pins

Input Pins

  • In – Frequency-domain input signal (complex).

Output Pins

  • Out – Reconstructed time-domain signal.
