Dentron MLA-2500 Question

Peak envelope power is the peak value of short term RMS power, average power is the short term average of RMS power. This is why for CW PEP and average power is the same, while for SSB and AM it is not. If you sustitute the word AVARAGE in place of RMS this will be correct. There is no such thing as RMS power. :) By RMS power, I mean the power derived from RMS voltage or current as opposed to using the PEAK value of voltage and/or current to determine power. I suppose I could have said effective or heating power, or power derived from RMS values of voltage or current. It gets too confusing when we say average power is the average of the average power. By the way, there is no such thing as avarage power. :-) 73 Tom |
