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 oscillator exhibits a varying reponsiveness to the driving frequency w that depends on ( (w_0)Â² - wÂ² ), which measures the closeness of w to the natural frequency in the same analytical way that the square of a standard deviation in statistical theory, and uncertainty in quantum mechanics are measured.
