Web7 de nov. de 2024 · First let’s look at loading resistance and the system. The wires in the cartridge have inductance. The cabling that goes from the tonearm to the phono section has capacitance. The inductance of the cartridge interacts with the capacitance of the cable, which forms a resonant energy spike at very high frequencies (MHz). WebTo overcome the limitation in time response, they effectively operate their layered gage in several different modes. At frequencies above 1500 Hz the rate of change of the temperature Tt is used to determine the flux as with the transient gages described earlier.
