... I thought it might be that, but it still makes no sense to me. Who or how does changing the direction of rotation of a rotating vector change its "size". Are you defining size as the rotation so that going from a + to a - is like reversing the direction of a vector? I think most people would consider the "size" of a vector to be the magnitude which is independent of phase angle and so rotation, no? Perhaps you can explain this with a little math? Not my gibberish, refer to the original posting ... -----ooooo----- From: "Brian Reay" Newsgroups: alt.engineering.electrical,uk.radio.amateur Subject: Phase noise Date: Sat, 13 Dec 2003 10:21:54 -0000 Message-ID: The term e^(-jwt) isn't some magical time machine relating to "minus time", e^(-jwt) is simply another way of writing 1/(e^jwt) which is a value that decreases as t increasing. |

See, he has trimmed his part, which clearly didn't refer to the true usage of negative frequency. I simply over estimated is ability to grasp the meaning of what I'd said without more detail. This was obvious as he also claimed claimed that division was impossible with complex numbers. He will attempt to drag this out, as he always does, but a look in the archive will show his claims to be nonsense. He drags this up from time to time, generally after a drubbing, He really doesn't like being proven wrong. Look at the date, he has been dragging this up with boring regularity since then. I've lost count of the times it has been explained to him. He has finally got the idea of the clockwise rotating phasor. He struggled with the idea that, as the phasor rotated, the angle became more negative, and thus decreased. eg -20 -10 |

You are correct in that you point out that I trimmed the post, and I did so to limit it to answer the question that was posed by Rickman There was nothing in Rickman's query about negative frequency so I do not see what it is that you are setting out to achieve by introducing that non-sequitur of a red herring? |

You been shot down again. You are hurling abuse, as you always do. Only you thinks otherwise. Everyone else is laughing at you. |

... You been shot down again. You are hurling abuse, as you always do. Only you thinks otherwise. Everyone else is laughing at you. Well, brian, once again I re-iterate that it is only you who is hurling abuse, just as you do above. Shame on you. Why do you behave like that when it is you who has repeatedly-ad-nauseam raised the spectre of DSP mathematics over the past week; why resort to rather silly and infantile abuse; why not discuss the technical matter that you have raised over and over again? Why resort to abuse when you have been challenged, for despite what you say, I do not? |

... He struggled with the idea that, as the phasor rotated, the angle became more negative, and thus decreased. eg -20 -10 Brian, is there some truth in G7FUJ, Cum's assertion that you were dismissed without references from your job as a mathematics teacher, for your confusion about a change in direction of a phasor as you express above would be very worrying? When you say "more", in "more negative" above, you are saying that the magnitude of the angle is increasing There seems to be a fundamental problem in your grasp of the direction of vectors, because there is nothing beween clockwise and anti-clockwise, left and right, up and down, or, in this case, negative and positive, for they are merely words used to disnmbiguate the direction of the vector. Brian, why don't you just give up whilst you are still behind? |
