| 词条 | Discrete frequency domain |
| 释义 |
A discrete frequency domain is a frequency domain that is discrete rather than continuous. For example, the discrete Fourier transform maps a function having a discrete time domain into one having a discrete frequency domain. The discrete-time Fourier transform, on the other hand, maps functions with discrete time (discrete-time signals) to functions that have a continuous frequency domain.[1][2] References1. ^{{cite book | title = DSP primer | author = C.
