This block adds a constant value to each item that passes through it. output[m] = input[m] + constant vector
Parameters
(R): Run-time adjustable
- IO Type
- Supported data types
- Complex
- Float
- Int
- Short
- Constant (R)
- The value to be added to the input stream. It must be of the same type as the block IO type.
- Vec Length
- Length of the vector
Example Flowgraph
This flowgraph shows the use of the Add Const and the Multiply blocks to create an amplitude modulated signal.
