Now if you can answer that correctly, then you will understand why a modulating signal that yields both 100% modulation on its peak and its average is unitelligable. If you answer that then we might go onto electronics for $200. james |

Brian Here is the jeopardy question for you: In the category of electronics for $100 Name the only signal that has the same value for its peak and average value? If he doesn't, does the question get thrown open to the opposing team for a bonus point? Oh, wait a minute... you are the opposing team :~) Now if you can answer that correctly, then you will understand why a modulating signal that yields both 100% modulation on its peak and its average is unitelligable. Even if he gets it, do you think that it's in his favor to accept the facts? His only product would become pointless, and any money and time invested will be lost. If you answer that then we might go onto electronics for $200. The problem is that this subject involves more than electronics. Human speech, hearing and interpretation is much more than simple decibel level. Do you really have the spare time to explain everything to him? If so, do you really want to be faced with legal action when his brain implodes? Regards, Peter. |
