Hardware vs Soft Motion Control: Cost & Performance Compared
OEMs traditionally used DSP-based hardware, plugged into a PC, for motion control. But new software-based solutions have challenged this approach, claiming equal or better performance at lower cost.
The inverse DFT (the IDFT) is given by
The inverse DFT is written using `
' instead of `
the result follows from the definition of the DFT, as we will show
in Chapter 6
