What it means: Thereâs blood in your pee, a condition called hematuria. That's never normal, so you should get it checked out as soon as possible,â Dr. Griebling says. Causes of bloody urine include trauma, kidney disease or cancer, inflammation or an infection in the kidneys, and more.
The most familiar AC waveform is the sine wave, which derives its name from the fact that the current or voltage varies with the sine of the elapsed time. Phase is a particular point in time on the cycle of a waveform, measured as an angle in degrees. A complete cycle is 360Â°. The waves are in phase if the waves are either 0 or 360Â° apart. The resulting amplitude (sum of the waves) is twice the original. They are out of phase if the resulting amplitude is between 0 and twice the original.
Another common sinusoidal waveform used in synthesis or measurement is the cosine wave, which is exactly the same shape as a sine wave and would sound exactly the same all by itself, but is distinguished by the fact that its cycle begins 90Â° out of phase to a sine wave, or at +1. ___________________. 1 Dodge p. 29-32.
