DSP Blockset

Continuous-Time Signals

Most signals in a DSP model are discrete-time signals, and all of the blocks in the DSP Blockset accept discrete-time inputs. However, many blocks can also operate on continuous-time signals, whose values vary continuously with time. Similarly, most blocks generate discrete-time signals, but some also generate continuous-time signals.

The sampling behavior of a particular block (continuous or discrete) determines which other blocks you can connect as an input or output. The following sections describe the behavior for two types of blocks:

• Source Blocks
• Nonsource Blocks

See the online block reference pages for information about the particular sample characteristics of each block in the blockset.
