Explanation by: Vinay
the absolute bandwidth is defined as the range of frequencies over which the signal has a non-zero power spectral density. for symbols represented as rectangular baseband pulses, the psd profile extends over an infinite range of frequencies, and has an absolute bandwidth of infinity.
