Receives a sequence of data bits, performs PAM modulation, and returns the modulated complex baseband waveform in the output complex waveform parameter.
PAM modulation involves mapping the input bit stream to PAM symbols (as specified by the PAM symbol map), interpolating by zero-insertion, and applying the pulse-shaping filter to the interpolated I/Q data.
If you use the finite impulse response pulse-shaping filters in modulation nodes, it may lead to the apparent loss of bits caused by filter delay. Refer to Filter Delay in the Details for more information about this effect. Set the flush buffers? parameter to TRUE to offset the effects of filter delay in single-shot operations or in the last iteration of continuous operations.
