A print engine assembly includes a support for a micro-electromechanical pagewidth print head. The invention relates to the seeds of soybean cultivar 4713487, to the plants of soybean 4713487, to plant parts of soybean cultivar 4713487 and to methods for producing a soybean plant produced by crossing soybean cultivar 4713487 with itself or with another soybean variety. A representation of the signal is produced at a lower frequency using digitization and filtering, and a continuous data representation of the band is processed using multiple-point samples to define the input to a complex FFT.
