Multiply Const

Multiplies the input stream by a scalar or vector constant (element-wise if vector).
output = input * constant
See Fast_Multiply_Const for a more performant version of this block for scalar values only.
Added in 3.8 If the constant is a scalar, the "Fast" version is automatically invoked (done behind the scenes).
Parameters
(R): Run-time adjustable
- Constant (R)
- Scalar or vector constant
Example Flowgraph
This flowgraph uses three Multiply type blocks. The top Multiply Const Block and middle Multiply Block are driven by the GUI Chooser to act as a Transmit / Receive switch. The bottom Multiply Const Block is a Volume control, the 'constant' being the 'volume' parameter from the QT GUI Range block.
Note: The lower section is a working 2 meter NBFM receiver.
