I recently saw an technical instrument that uses electromagnetic field to capture and move small objects. For example it can be used to capture and unscrew nut(female screw). How this instrument can be named right to find its description in the Internet?
For example our PC generates signal with 3V voltage. The task of elictricity generating plant is to raise voltage (for example up to 3000V) and give it to its output. Than we use transformer that decreases signal back to 3V and feed it to A-to-D converter to check the signal.
Jim Hardy, it is real experiment.
And we need an answer to the question: is it possible to find a function that goes to input of electricity generating plant such that at the ouput we get sine with constraint difference between main harmonic and any other from the first eleven not less than...
Yes, Iwant to reduce distortion so that constraint "difference between main harmonic and any other from the first eleven not less than 52 decibel" was true.
We have a PC with digital-to-analog converter. With help of this converter we generate “pure” sine: y(t)=A*sin(2π*f*t+ ψ) with industrial frequency 50 Hz. This signal goes as input to electricity generating plant which has a goal to raise this signal and give to its own output. During this...
