Notes about the FTD file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The FTD file type is primarily associated with 'FFTDesigner' by RHDC Services Ltd..
FFTDesigner is a Fourier Fast Transform simulator that allows you to gauge performance using a number of standard window functions.
Fast Fourier Transform is an efficient algorithm to compute a specific kind of mathematical transform of signals between domains, taking a reoccurring function that displays the same output at regular intervals and decomposes it into the sum of a set of simple oscillating functions.
