As discussed in Note 60, many DSP applications require the creation of the analytic-like signal that corresponds to some real-valued signal of interest. This note describes just one of several approaches that can be used to generate an analytic-like signal. For an overview of other possible approaches, refer to Note 60.

For a real-valued sequence, *x*[*n*], the corresponding analytic-like sequence, *x*_{a}[*n*], can be formed as

**61.1**

where

and *H*{·} denotes the discrete Hilbert transform. ...
