A question about radio, sound, "wave length" etc.

The definition of peak to peak must have changed since I was in A school. I was taught that positive peak to negative peak or negative peak to positive peak shal be called peak to peak. (Neener Neener) Sure. I don't disagree. Usually the term "peak to peak" relates to amplitude measurements. But, a positive peak to the next negative peak is 180 degrees if you are looking for frequency over a time period. A positive peak to the next positive peak is 360 degrees. Or negative to the next negative. Or any other point to the next repeating point on the waveform. Eisboch 360 degrees= 1 cycle is the description I was looking for. Quit trying to confuse me with facts. Check tonights Tampa news videos. Actually may not be 360 degrees. What if it is a square wave? In that case you would probably be talking PRR. This discussion is starting to get over my head so I'll bow out and let you engineers have at it. Giving you a sinuous headache? :-) No. But i am experiencing sinusoidal disenchantment |
