The interface is the means by which a user communicates with a system whether to get it to perform some function or computation directly eg compute a trajectory change a word in a text file display a video. The user input is made by pressing keys or buttons or responding verbally to the interface.

Four areas can compose this interface.
. Implementation details There are many ways to define the DFT varying in the sign of the exponent normalization etc. A MODBUS backend interface can be provided allowing indirectly the access to user application objects. A pre-mapping between this interface and the user application data has to be done local issue.
Input discrete output discrete coils input registers and output registers. Because the discrete Fourier transform separates its input into components that contribute at discrete frequencies. To find and deliver information eg getting a paper from the Web or information from a database.
The output is called a spectrum or transform and exists in the frequency domain. Voice user interfaces which accept input and provide output by generating voice prompts. In this implementation the DFT is defined as A_k.
Web-based user interfaces or web user interfaces WUI that accept input and provide output by generating web pages viewed by the user using a web browser program. Or to provide ways of interacting with other people eg.
