  • For example, if the carrier signal is 200 Khz, the modulation frequency is 10 Hz (this could for example be the rate at which the finger touches the multi-touch panel), the signal to be demodulated would look like a amplitude modulated signal, i.e. have a peak at 200 Khz and one peak each at 200 Khz???10 Hz and 200 Khz+10 Hz.
