Abstract
Mixing, modulation and demodulation using the nonlinear properties of microelectromechanical resonators and filters are described. Mixing followed by filtering is implemented using microelectromechanical filters with nonlinear input transducers. AM modulation is implemented by passing a carrier signal through the output transducer of a microelectromechanical filter. FM and FSK demodulation is accomplished using parallel banks of microelectromechanical filters. The invention can be implemented using integrated circuit technology.
