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 input is a not a vector, the "Fast" version is automatically invoked (done behind the scenes).
- Constant (R)
- Scalar or vector constant. If the input is a vector, this parameter must be a vector of the same size. To multiply all the input items by the same value, use Fast_Multiply_Const.
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.
