# MT Upconvert Baseband (MT Upconvert Baseband (Real)) (G Dataflow)

Version:

Upconverts baseband I/Q (complex envelope) signal data to its real passband equivalent. You can use this node with simulated data. The function operates independently of your hardware settings.

## baseband waveform

The complex envelope signal data for upconversion to its passband equivalent.

### t0

The trigger (start) time of the acquired signal.

Default: 0.0

### dt

Time interval between data points in the acquired signal.

Default: 1.0

### Y

The complex-valued time-domain data array. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively.

## carrier frequency

The center frequency of the passband, in hertz (Hz). The incoming signal is upconverted to center around this frequency. Specify the desired carrier frequency of the outgoing signal with this parameter.

## error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

## reset?

A Boolean that determines whether to use the value specified in the initial phase parameter.

 TRUE The node uses the initial phase value. FALSE The node ignores the initial phase value and continues using values supplied in the previous call. Reusing previous input values is useful when sequential data blocks represent contiguous signal data.

Default: FALSE

## initial phase

The initial phase, in degrees, of the software local oscillator used in the upconversion process. The node ignores this parameter if you set the reset? parameter to FALSE. Use the initial phase parameter to match the phase of the incoming modulated carrier and the local oscillator(s) of the upconversion process.

## passband waveform

The upconverted signal in passband form.

## error out

Error information.

The node produces this output according to standard error behavior.

## Upconvert Baseband Formula

If the input complex waveform is represented as the following equation,
$m\left(t\right)=\mathrm{Re}\left[m\left(t\right)\right]+j×Im\left[m\left(t\right)\right]$
where $j=\sqrt{-1}$ and Re() and Im() denote the real and imaginary parts of m(t), respectively, then the generated passband waveform m PB (t) of this node is represented by the following equation:
${m}_{PB}\left(t\right)=\mathrm{Re}\left[m\left(t\right)\right]\mathrm{cos}\left(2{f}_{c}t\right)-Im\left[m\left(t\right)\right]\mathrm{sin}\left(2{f}_{c}t\right)$
where f C denotes the carrier frequency corresponding to the generated passband waveform.
