mCalc

App name -mCalc This app calculates Discrete Fourier transforms Inverse discrete Fourier transforms Convolutions of sequences. Very 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 in between 2 numbers. Errors occur if you type something like - "1,5". The correct format is "1 5" :)
