A battery-operated device comprises: a first battery cell having a voltage; a second battery cell having a voltage; a first anti-aliasing filter operable to be coupled to the first battery cell; a second anti-aliasing filter operable to be coupled to the second battery cell; an analog-to-digital converter operable to be coupled to the first anti-aliasing filter during a first period of time or the second anti-aliasing filter during a second period of time different than the first period of time; and wherein the second anti-aliasing filter is charged during the first period of time and the first anti-aliasing filter is charged during the second period of time.

The present disclosure relates to near-end crosstalk (NEXT) cancellation. A transmit communication signal is transmitted over a first Digital Subscriber Line (DSL) connection using a first group of frequencies and a receive communication signal is received over a second DSL connection using a second group of frequencies that at least partially overlaps the first group of frequencies. A crosstalk correlation between the first and second communication signals is determined. Based on the crosstalk correlation, a crosstalk cancellation signal is generated. The crosstalk cancellation signal is subtracted from the second communication signal, with the intention of reducing NEXT.

A battery powered system includes a voltage level shifter, an anti-aliasing filter, a pair of switches, a unity gain differential buffer, a second pair of switches, and an analog-to-digital converter. The first pair of switches couple the differential output port of the voltage level shifter to the differential input port of the anti-aliasing filter. The second pair of switches couple the differential output port of the anti-aliasing filter to the differential input port of the unity gain differential buffer. The analog-to-digital converter is coupled to the differential output port of the unity gain differential buffer.

A cascaded integrator-comb (CIC) decimation filter includes N integrator stages, N1 differentiator stages, and a decimator coupled to receive an integrated signal that is output from the N integrator stage and generate a decimated signal that is input to the N1 differentiator stages. The decimator periodically asserts an integration reset signal. A last integrator stage of the N integrator stages is reset in response to assertion of the integration reset signal.

A digital-to-analog conversion circuit (DAC) is operable to convert an input digital signal to an output analog signal. The DAC comprises a digital signal processing circuit operable to process the input digital signal according to a first transfer function to generate a first processed digital signal and process the digital input signal according to a second transfer function to generate a second processed digital signal. The DAC comprises a first unit DAC operable to convert the first processed digital signal to a first intermediate analog signal, and a second unit DAC operable to convert the second processed digital signal to a second intermediate analog signal. The DAC comprises switching circuits and a combiner circuit to generate the output analog signal from the intermediate analog signals.

An instrument for performing order analysis on a rotational machine. An input module receives periodic motion data, and machine characteristic data that is associated by time with the periodic motion data. A processor module receives the periodic motion data and the machine characteristic data, applies a Goertzel module to the periodic motion data and the machine characteristic data, and thereby creates an order data set comprising magnitude of machine characteristic data versus order of normalized periodic motion data.

This application presents an adaptive data recovery from distorted signals (ADRDS) of original data symbols from intervals or parameters of tone signals derived from a received OFDM signal, including responding to dynamic distortions introduced to the received OFDM signal by an OFDM transmission channel. Such ADRDS is implemented by converting back the derived intervals or parameters into original data symbols corresponding to distinctive sets of the intervals or parameters which the derived intervals or parameters belong to.
