Answer by jpa for Why is energy zero at zero bandwidth?
Power density graph does not work for signals that have infinitely narrow peaks.If you had a signal with a continuous static frequency and plotted the power density of it in infinite resolution, the...

The curves represent energy (or power) densities; thus, energy is what you get when you integrate them over a range. For example, you could get the power in the range 1000 Hz to 2000 Hz by integrating...

Why is energy zero at zero bandwidth?
From the video lecture on noise analysis by Razavi here. Can anyone explain in more detail what Razavi said here? Why is the energy at a single frequency (zero bandwidth) zero?Lets look at the energy...
