DSP Blockset

Nonsource Blocks

All nonsource blocks in the DSP Blockset accept discrete signals, and inherit the sample period of the input. Others additionally accept continuous-time discrete signals.

Discrete-Time Nonsource Blocks.   Discrete-time nonsource blocks can accept only discrete-time inputs, and generate only discrete-time outputs. Examples are all of the resampling and delay blocks, including Upsample and Integer Delay. A discrete-time nonsource block inherits the sample period and sample rate of its driving block (the block supplying its input). For example, if the driving block's sample period is 0.5 second, the inheriting block also executes at 0.5 second intervals. Simulink generates an error if a continuous input is connected to a discrete-only block.

Continuous/Discrete Nonsource Blocks.   In the continuous/discrete blocks, continuous-time inputs generate continuous-time outputs, and discrete-time inputs generate discrete-time outputs. Examples are the Complex Exponential and dB Gain blocks. The nonsource triggered blocks such as Triggered Delay Line are also in this category.
