System object: dsp.DigitalUpConverter
Process inputs using the digital up converter
Y = step(H,X)
Y = step(H,X) takes a real or complex input column vector X and outputs an up sampled and frequency up converted signal Y. X can be of data type double, single, signed integer, or signed fixed point (fi objects). The length of Y is equal to the length of X multiplied by the InterpolationFactor. When the data type of X is double or single precision, the data type of Y is the same as that of X. When the data type of X is of a fixed point type, the data type of Y is defined by the OutputDataType property.
