Multiplies input stream by a constant.
output = input * constant scalar/vector (element-wise if vector)
See Fast Multiply Const for a more performant version of this block.
Parameters
(R): Run-time adjustable
- Constant (R)
- Constant to multiply the input stream by
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.
