You are *not* claiming that the *energy* from the reflected wave is dissipated in the source resistor, because for the *energy* in the reflected wave to be dissipated in the source resistor, the *energy* would have to dissipate at the same time that the reflected wave delivered the *energy*, and the analysis of instantaneous *energy* flows shows that this is not the case. I clearly stated that my claim is based on a special case zero interference condition - it's even in the title of the article. The instantaneous energy that you (not I) introduced, does not meet the zero interference precondition. Therefore, anything that does not meet the zero interference precondition that I enumerated is an irrelevant diversion. You introduced that irrelevant straw man and tried to make hay out it. :-) you are saying that the average reflected power is numerically equal to the increase in the average dissipation in the source resistor. I can accept that as correct. Finally, after a million words. :-) You might consider rewriting the sentence "reflected energy from the load is flowing through the source resistor, RS, and is being dissipated there" since it refers to the energy in the reflected wave and may mislead others in the same way it mislead me. Since "average reflected power" is dependent upon the "reflected energy", I don't see any problem. Would "average reflected energy" work for you? It should be obvious that, associated with interference during each cycle, destructive interference energy is stored during part of the cycle and delivered back as constructive interference energy during another part of the cycle. The intra-cycle interference averages out to zero. Many have objected to the term "reflected power" saying it is not power that is reflected but instead is "reflected energy". So I stopped talking about "reflected power" and started talking about "reflected energy". Now you object to the use of the term "reflected energy". Would you and the rest of the guru attack gang please get together on what term you would like for me to use? -- 73, Cecil http://www.w5dxp.com |
