Abstract: A method and system for converting an optical signal to electrical information signals, including demodulated baseband information signals and modulated baseband signals at multiple harmonics. In an embodiment, the optical information signal is amplitude modulated with information. The method converts an optical signal to electrical charge, accumulates the electrical charge, and periodically transfers the accumulated electrical charge to a storage device, whereby the periodically transferred electrical charge forms the electrical signals. An exemplary system includes an optical transducer and a universal frequency translator coupled to an output of the optical transducer. The optical transducer receives an optical signal and converts the optical signal to electrical charge. The universal frequency translator periodically transfers energy from the electrical charge and forms the electrical signals from the transferred energy.

Abstract: In accordance with the preferred embodiment of the present invention, an electronic component is modeled. Performance of the electronic component is measured to produce a plurality of data vectors representing actual performance of the electronic component. Boundary vectors are selected from the plurality of data vectors. A density estimate is calculated for each data vector in the plurality of data vectors. A first selected number of the data vectors are partitioned from the plurality of data vectors into a partitioned group. The partitioned group includes the first selected number of data vectors from the plurality of data vectors with greatest density estimates. A second selected number of the partitioned group is selected as candidates for boundary vectors. The candidates for boundary vectors include the second selected number of the partitioned group with lowest density estimates. The boundary vectors are selected from the candidates for boundary vectors.
