MT Modulate FM v2 (Deprecated)
Performs frequency modulation on an RF carrier wave according to a baseband information signal input to the message signal control. It returns the complex envelope of the FM modulated signal in the FM modulated waveform indicator.
 |
message signal contains the message signal used to modulate the carrier wave. |

 |
FM deviation specifies the desired frequency deviation of the frequency-modulated signal returned in the FM modulated waveform parameter. |

 |
reset? controls initialization of internal VI states. The modulation process involves an integration operation. When reset? is FALSE (default), the integration begins in the final state from the previous call (this option is useful when the current block of I/Q data is contiguous with the preceding block of I/Q data). When this parameter is TRUE, the initial state of the integration is set to zero at each call to this VI. |

error in accepts error information wired from previously called VIs. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.

FM modulated waveform contains the baseband signal data and the complex envelope of the frequency-modulated signal.

error out passes error or warning information out of a VI to be used by other VIs. Right-click the front panel error out indicator and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.

Details
This VI performs signal processing on data and operates independently of hardware settings. This VI can be used in simulated as well as hardware-equipped applications.
The output frequency-modulated wave is described by the equation:
This VI sets carrierPhase in the equation above to zero. To adjust the carrier phase, use the initial phase input of the MT Upconvert BasebandVI VI.
Using MT Modulate FM v2.vi in Modulation Toolkit 4.1
The Modulation Toolkit 4.0 version of the MT Modulate FM VI has been renamed to MT Modulate FM v2 and has been moved to the deprecated folder at <LabVIEW>\vi.lib\addons\Modulation\Analog\Deprecated. If your application currently refers to MT Modulate FM, the application will use the optimized Modulation Toolkit 4.1 version of this VI.
