Hi, I am studying the possibility of using the FDM technique for an array of capacitive sensors. I have multiple capacitive sensors and each of them has a wire for stimulating it with a sinusoidal signal and reading the output. Being a lot of sensors and therefore tracks, I need to reduce the number of tracks. I am thinking to use a FDM technique in other to stimulate each of them with a sinusoidal signal at different frequency and then read the output through a single channel with demodulation. could it be done?
