You can use discrete-spectrum signal representation to analyze distortion due to spectral regrowth in nonlinear devices, such as those found in wireless-communications systems. However, this technique introduces errors in both output bandwidth and power estimation of the spectral regrowth. Torben Larsen of Aalborg University, Denmark, shows how the bandwidth error may be large, but is predictable.
