Mercury is a naturally occurring element that is found in air, water and soil. Exposure to mercury â even small amounts â may cause serious health problems, and is a threat to the development of the child in utero and early in life. Mercury may have toxic effects on the nervous, digestive and immune systems, and on lungs, kidneys, skin and eyes.
An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to an alternating current signal.
The phase oscillator. A phase oscillator is an oscillator model where we view the state of the system as going around the simplest loop, a unit circle. In a phase oscillator model, the state variable $\theta$ is called the phase of the oscillator. The state space in which the phase $\theta$ lives is the interval $[0, 2\pi]$.
