摘要： An authenticating circuit includes a first and second challenge vector input, a first and second highly variable process-dependent circuit and a logic circuit. The first highly variable process-dependent circuit receives a first vector from the first challenge vector input and generates a first output that is a function of the first vector and at least one process-dependent feature of a component of the first highly variable process-dependent circuit. The second highly variable process-dependent circuit receives a second vector from the second challenge vector input and generates a second output that is a function of the second vector and at least one process-dependent feature of a component of the second highly variable process-dependent circuit. The logic circuit generates a response output that is a function of the first output and the second output. The function operates so that the response output is independent of environmental conditions of the authenticating circuit.

摘要： The presently invention is directed to ways to measure distortion effects while allowing for the possibility of significant reduction in test cost. An exemplary embodiment of the present invention provides a method for amplifier distortion measurement including comparing a first amplitude response of an output signal from a power amplifier to a second amplitude response of a reference input signal to determine a set of Amplitude-to-Amplitude (“AM-AM”) distortion values. Additionally, the method for amplifier distortion measurement includes equalizing the first amplitude response of the output signal to match the second amplitude response of the reference input signal based on the set of AM-AM distortion values and creating a difference signal based on a comparison of the equalized output signal to the reference input signal. Furthermore, the method for amplifier distortion measurement includes calculating a set of Amplitude-to-Phase (“AM-PM”) distortion values based on a third amplitude response of the difference signal.

摘要： A method and device prevent a set-top terminal from accepting a download of new programming or data over a cable network when the download would be redundant of information already possessed by the set-top terminal or would cause an inconvenience to subscribers. When the set-top terminal is signaled that a new download is being offered, the set-top terminal checks to see if the download in fact contains a newer version of data or programming than is currently resident in the set-top terminal. The set-top terminal also checks whether criteria for accepting a download are met. The criteria are conditions that tend to indicate that an interruption of service to accept a download would not inconvenience the subscriber at that time. When the criteria are met, the download is accepted. Otherwise, the download is not accepted or is not accepted until the criteria are satisfied. Similar criteria govern the termination of the older, executing programming and the execution of the newer, downloaded programming to, again, prevent unwarranted disruptions in service.

摘要： A bit error rate test on a transceiver is accelerated by adding a phase offset to data phase encoding and decoding in the transceiver and by mapping bit error rate test results from an elevated error rate condition to a normal error rate condition for the transceiver. The elevated error rate is accomplished by adjusting the phase of the phase encoder and decoder with the value of the phase offset so that the encoded data transmission signal is not as robust against noise as it normally would be. Noise in the form of an interference signal is introduced during the transmission, and the bit error rate is measured after the receiver has decoded the signal. The bit error rate (BER) data with an elevated propensity for error is mapped against bit error rate data for normal operations. A mapping function is built to map BERE (bit error rate elevated) data—data from the elevated error rate condition for data encoding, to BERN (normal bit error rate) data—data from the normal error rate condition for data encoding. The BERE data is mapped to BERN data using the mapping function so that the BER performance of the transceiver may be measured using far fewer test sequences of digital bits.
