Energy spectral density defines(a) Signal energy per unit area(b) Sign

1.	Energy spectral density defines(a) Signal energy per unit area(b) Signal energy per unit bandwidth(c) Signal power per unit area(d) Signal power per unit bandwidthI have been asked this question during an online exam.This question is from Spectral Density and Autocorrelation in portion Signals and Spectra of Digital Communications
Answer» The correct answer is (b) Signal ENERGY per unit bandwidth The explanation is: Energy SPECTRAL density gives the signal energy equal to the AREA under the waveform energy spectral density versus frequency curve.
