When these half-length transforms are successively decomposed, we are left with the diagram shown in the bottom panel that depicts the length-8 FFT computation.

Web•Thus, the FFT processor requires careful scaling –Floating point number representation •Easiest conceptually, but expensive hardware. Typically not used in efficient DSP … Webfollowing discussion on "How the FFT works" uses this jargon of complex notation. That is, the singular terms: signal, point, sample , and value , refer to the combination of the real part and the imaginary part. The FFT operates by decomposing an N point time domain signal into N time domain signals each composed of a single point.
