DFT Calculator

This app calculates DFTs, IDFTs and Convolutions

App name -mCalc

This app calculates Discrete Fourier transforms Inverse discrete Fourier transforms Convolutions of sequences.

Useful in Digital Signal Processing

HOW TO USE:

For eg. If you want to calculate Inverse discrete Fourier transform for the sequence: 1+2i, 2+4i, 3.5-6i

1. Choose "iDFT" from the drop-down menu

2. In the first input box type the REAL part of the sequence ie. "1 2 3.5"

3. In the second input box type the IMAG part of the sequence

ie. "2 4 -6"

4. Click Calculate

5. See the answer

*Remember! You have to put a SPACE in between 2 numbers. Errors occur if you type something like - "1,5". The correct format is "1 5" :)
