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.

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.
