Receives a complex-valued waveform, divides it into segments of (trellis length / symbol rate), and displays those segments as a trellis diagram on a standard waveform graph.
For a "clean" diagram with distinct, nonshifting transitions, the input waveform must have an integer-valued symbol-rate-to-sample-rate ratio.
Modulated data for plotting on a trellis diagram.
Trigger (start) time of the Y array.
Time interval between data points in the Y array.
The complex-valued signal-only baseband modulated waveform. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively.
The desired symbol rate, in hertz (Hz).
Number of symbol periods on the horizontal scale of the trellis diagram.
Modulation index of the input waveform. The default is appropriate for MSK modulation.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Default: no error
An array of waveform segments for trellis diagram display. Each segment has a time length of (trellis length × symbol period) seconds. Wire this parameter directly to a waveform graph.
Time of first value in the phase array.
Time between values in the phase array.
Unwrapped phase of the input waveform.
The node produces this output according to standard error behavior.
