Experienced users annotate their with red pen or digital highlights. The most common modifications include: inside the metal detector pdf
This is the section most PDFs struggle to explain clearly. The demodulator compares the transmitted signal (reference) to the received signal (target). Metals behave like resistors (eddy currents) and inductors (permeability). The phase shift tells the detector if you have a nickel, a gold ring, or iron junk.
