摘要： An apparatus and method for detecting a target environmental variable (TEV). A first film-bulk acoustic resonator (FBAR) oscillator that includes a first FBAR with a first response to the target environmental variable generates a first frequency. A second film-bulk acoustic resonator (FBAR) oscillator that includes a second FBAR with a second response to the target environmental variable generates a second frequency. A circuit that is coupled to the first FBAR oscillator and the second FBAR oscillator determines the target environmental variable (e.g., changes in the TEV) based on the first frequency and the second frequency.

摘要： Systems and methods of detecting wireless channel status from acoustic discrimination of spectral content are described. In one aspect, a wireless system includes a spectrum analyzer, a detector, and a controller. The spectrum analyzer is operable to acoustically discriminate spectral content of an input electrical signal in multiple discrete frequency channels. The detector is operable to determine respective statuses of the frequency channels from the acoustically discriminated spectral content. The controller is operable to select one of the frequency channels based on the determined statuses of the frequency channels.

摘要： A demodulator with a filter having a reduced number of filter taps without a sacrifice in filter accuracy. The demodulator includes elements that generate a data stream that carries a component of an input signal in response to a data stream that carries samples of the input signal. The demodulator also includes elements that generate a sample clock for sampling the input signal such that the sample clock is preselected to cause the data stream that carries the component to carry alternating samples that are substantially equal to zero. The filter in the demodulator has a set of filter taps which are arranged to tap only the samples in the data stream that carries the component that are not substantially equal to zero.
