I don't know that. Manipulating EM signals seems like using forces of nature in a controllable manner.
It depends. If the manipulation is ADC + multiplying by two in an FPU + DAC, I say it isn't, we already know how to build circuits for that, and we know what happens to a signal multiplied by two.
But surely I am still using forces of nature in a controllable manner, even if my use is entirely known???
If you discover a new quartz crystal that will changed phase of signal by 10% then it's probably patentable.
Ok, but if I program a DSP chip to realize the same phase change it is not patentable? Why? What is the difference in effect produced by these two things?
Kind regards,
