No, not exactly. Addition is a linear process and produces no frequencies in the output of the summation which are not present in the input. A nonlinear process is commonly applied to the summation to create beats. For example putting a summation of sine wave voltages onto a diode would produce a

So the addition of frequencies requires that the input signal already contains a non-linear component. and for entirely linear input the frequencies would not be additive. Harry On Sun, Oct 18, 2020 at 12:08 PM Bob Higgins wrote: > To get frequencies in the output that were not in the input requ

To get frequencies in the output that were not in the input requires a nonlinearity. If you model the nonlinearity using a series such as Y = a + bX + cX^2 + dX^3... then all of the terms with X^2 and greater are the nonlinear terms. Usually the coefficient of the squared term, c, is the largest o

If cold is a thing, then perhaps the laser is a cold pump and what is being extracted are longer (cooler) wavelength vibrations from the electrode, thereby increasing the electrode's capacity to absorb shorter (hotter) wavelengths from the laboratory surroundings. These hotter wavelengths then ena

Hi, When two waves of different frequencies combine the result is a third wave with a beat frequency corresponding to the difference between the two original frequencies. A wave model can show how this happens, but I don't see how it can bring about the addition of frequencies. Can someone model t
