摘要: An apparatus is provided. The comprises a digital signal generator, an analog filter, amplitude modulator, and analog-to-digital converter (ADC). generator has demodulator provides excitation signal. filter coupled to the generator. modulator variable capacitor filter. also generates modulated with that function of capacitance capacitor. ADC demodulator, operate synchronously.
