摘要： Circuitry for providing non-uniform analog-to-digital (“A/D”) signal conversion for wideband signals is provided. The circuitry of the invention is optimized for wideband signals because it does not sacrifice the small-scale resolution of high-probability signal amplitudes while preventing the clipping of low-probability signal amplitudes. The circuitry includes a nonlinear amplifier and an A/D converter that may be uniform or non-uniform. The digital output of the A/D converter may be further processed by circuitry that has an output function that is the inverse of that of the nonlinear amplifier, so as to maintain linear A/D conversion.

摘要： A cable tester tests cable and determines a cable pass/fail status. A pretest module senses activity on the cable and selectively enables testing based on the sensed activity. A test module is enabled by the pretest module, transmits a test pulse on the cable, measures a reflection amplitude, and calculates a cable length. The cable status includes an open status, a short status, and a normal status. The test module determines the cable status of the cable based on the cable at least one of passing and failing A out of B cable tests. The test module determines the cable status for each of the B tests based on the measured amplitude and the calculated cable length.

The method generally includes interleaving sections of a control sequence with bits of the information. The software and receivers are generally configured to implement one or more aspects of the methods disclosed herein, and the systems generally include those that embody the inventive receivers disclosed herein. The present invention is particularly useful in powerline channels, where certain parameters (such as noise) have time-dependent or periodic variations in value. By distributing the control sequence, the incidence of carrier recovery is reduced, the likelihood of successful packet or frame transmissions is increased, and data may be more reliably communicated.

摘要： A digital signal processor includes an up-sampling module that samples an input signal and generates up-sampling points. A natural sampling module includes a reference signal generation module that generates a reference signal. A crossing point detection module receives the up-sampling points and the reference signal and uses interpolation to detect intersection points of the input signal and the reference signal. The crossing point detection module determines values of the input signal at first and second evaluation times. The crossing point detection module estimates a current intersection point of the input signal and the reference signal as an intersection of the reference signal and a line that extends between first and second points on the input signal that correspond with the first and second evaluation times. A frequency of the reference signal is variable and a current switching period of the reference signal is not equal to a previous switching period.

Removing the image signal can include using one or more weights to control one or more filters to resolve the desired signal. The one or more weights can be determined based on the noise signal.

摘要： Methods and systems for filtering an input signal include receiving a first demodulated signal produced by multiplying a first generated signal with a received input signal, receiving a second demodulated signal produced by multiplying a second generated signal with the received input signal, and producing first and second filtered output signals by applying a transfer function to the first and second demodulated signals, wherein the transfer function comprises a first filtering coefficient, wherein the first filtering coefficient defines a matrix comprising one or more non-symmetrical terms. An application of the transfer function can compensate for one or more of an amplitude mismatch between the first and second generated signals, a phase mismatch between the first and second generated signals, and one or more frequency handling characteristics of channels used to produce the first and second demodulated signals.
