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.
An oscilloscope is a laboratory instrument commonly used to display and analyze the waveform of electronic signals.irtually all oscilloscopes have adjustable horizontal sweep and vertical deflection settings. The illustration shows two common waveforms as they might appear when displayed on an oscilloscope screen. The signal on the top is a sine wave; the signal on the bottom is a ramp wave.
