Revision as of 09:27, 25 August 2022

This block adds a constant value to each item that passes through it. output[m] = input[m] + constant vector

Parameters

(R): Run-time adjustable

Constant (R)
The entered value must be of the same type as the input / output ports (i.e. complex, float, etc.).

Example Flowgraph

This flowgraph shows the Add Const and Multiply blocks to create an amplitude modulated signal.
