    open interval?

    A Boolean that specifies the interval over which this node resamples the input signal.

    True This node uses an open interval.
    False This node uses a closed interval.

    Default: False

    datatype_icon

    signal

    The input signal.

    This input can be a waveform or an array of waveforms.

    datatype_icon

    resampled dt

    The sampling interval, in seconds, between data points in the resampled signal.

    Default: 1

    datatype_icon

    resampled t0

    Start time value for the resampled signal.

    datatype_icon

    interpolation mode

    Algorithm this node uses to resample the input signal.

    Name Value Description
    coerce 0 This node sets each output sample value to the input sample value that is closest to it in time.
    linear 1 This node sets each output sample value to the linear interpolation between the two input samples that are closest to it in time.
    spline 2 This node uses the spline interpolation algorithm to compute the resampled values.
    FIR filter 3 This node uses a finite impulse response (FIR) filtering algorithm to compute the resampled values.

    Default: linear

    datatype_icon

    error in

    Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

    Default: No error

    datatype_icon

    FIR filter specifications

    Minimum values this node needs to define the FIR filter.

    This input is valid only when you set interpolation mode to FIR filter.

    datatype_icon

    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

    datatype_icon

    normalized bandwidth

    Fraction of the new sampling rate that is not attenuated.

    Default: 0.4536

    datatype_icon

    resampled signal

    Resampled signal.

    This output can return a waveform or an array of waveforms.

    datatype_icon

    used t0

    Actual start time of the resampled signal.

    datatype_icon

    error out

    Error information. The node produces this output according to standard error behavior.

    datatype_icon

    t0 adjusted warning?

    A Boolean that indicates whether the actual start time of the resampled signal equals the start time value you specified.

    True The actual start time of the resampled signal does not equal the start time value you specified.
    False The actual start time of the resampled signal equals the start time value you specified.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
