Resample (Constant to Variable) (G Dataflow)

A Boolean that specifies the initialization of the internal state of the node.

This node automatically initializes the internal state to zero on the first call and runs continuously until this input is True.

Default: False

Input signal for resampling.

The sampling interval of signal is 1.

This input accepts the following data types:

• Waveform
• Waveform in complex double-precision, floating-point numbers
• 1D array of waveforms
• 1D array of waveforms in complex double-precision, floating-point numbers
• 1D array of double-precision, floating-point numbers
• 2D array of double-precision, floating-point numbers
• 1D array of complex double-precision, floating-point numbers
• 2D array of complex double-precision, floating-point numbers

Time instances for resampling in ascending order.

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

Minimum values this node needs to specify the FIR filter.

alias rejection (dB)

Minimum attenuation level of signal components aliased after any resampling operation.

If alias rejection (dB) is less than 48, this node uses 48 instead.

Default: 120

normalized bandwidth

Fraction of the new sampling rate that is not attenuated.

Default: 0.4536

A Boolean that determines whether the input signal undergoes lowpass filtering when this node downsamples the signal.

If anti-aliasing is True, this node protects the resampled signal from aliasing. However, the computation requirements increase during resampling.

Default: True

Resampled signal.

This output can return the following data types:

• 1D array of double-precision, floating-point numbers
• 2D array of double-precision, floating-point numbers
• 1D array of complex double-precision, floating-point numbers
• 2D array of complex double-precision, floating-point numbers

Time instance for each sample in the resampled signal.

The number of elements in timestamps is equal to the number of columns in resampled signal. The contents of the time input determine the contents of timestamps. As a result of the internal state of the resampling filter, timestamps might have additional data at the beginning of the array and might lose some data at the end of the array.

Error information.

The node produces this output according to standard error behavior.
