inorganic chemistry - In Crystal Field Theory what does Δo=10Dq mean?


While studying the Crystal Field Theory I was told Dq is a unit, related to the unit ΔO by the relation ΔO=10 Dq. But aren't ΔO and Dq variables, not units? The unit is of energy, such as eV or Joules, these are symbols to represent a particular value of energy, which could be anything. So what do we mean when we say ΔO=10 Dq? What exactly is Dq (I haven't been able to find this in any of my textbooks, they just either state this relation, or not at all) and are they actually units of energy?

I have a question about matched filtering. Does the matched filter maximise the SNR at the moment of decision only? As far as I understand, ...
