Power density versus power density spectrum
hello friends,
A little doubt while reading noise in electronic devices. Is there any difference in the physical interpretation of power density and power density spectrum.
why there is a resistance term relating the two quantities. I am discussing the case where I have to compute the resistor noise.
regards,
proffy

Jeffrey ArulrajPower density spectrum is the plot where frequency is specifically chosen as a reference plane along x axis to plot power density
Power spectrum is analysing power of the signal over any reference plane it can be time, temperature or even pressure and the like
Hope you get a picture
