Abstract: In an embodiment, a channel estimator includes first and second stages. The first stage is operable to generate a respective one-dimensional array of first channel-estimation coefficients for each communication path of a communication channel, and the second stage is operable to generate a multi-dimensional array of second channel-estimation coefficients in response to the first channel-estimation coefficients. For example, such a channel estimator may estimate the response of a channel over which propagates an orthogonal-frequency-division-multiplexed (OFDM) signal that suffers from inter-carrier interference (ICI) due to Doppler spread. Such a channel estimator may estimate the channel response more efficiently, and with a simpler algorithm, than conventional channel estimators. Furthermore, such a channel estimator may be able to dynamically account for changes in the number of communication paths that compose the channel, for changes in the delays of these paths, or the portions of the transmitted symbol energy carried by these paths.

Abstract: Configurable flip-flop cells for use in scan chain configurations include one or more multiplexers, a flip-flop, and one or more logic gates. The logic gates are configurable, through modification of different metallization or semiconductor layers, to operate as spare gates or to disable flip-flop cell outputs based selection signal switching between scan shift and capture mode. When disabling flip-flop cell outputs, the logic gates are configured to receive both a test signal and a data input signal and select one of the two to pass to the flip-flop based on the selection signal. When used as spare gates, the logic gates receive external inputs and provide spare gate outputs to circuitry on an integrated circuit that is external to the flip-flop cells.

Abstract: Composite materials having conductive properties are described for use in testing circuits and in manufacturing electrical switches. The composite materials described, when in an unstressed state, generally behave as insulators. However, when sufficient mechanical pressure is applied to portions of the composite materials, the portions to which the mechanical pressure is applied become increasingly conductive. Methods for testing a PCB using composite material switches are also disclosed. A sheet that includes a composite material may be used to test electrical functionality of various regions on a PCB by way of local pressure application. The sheet may be easily applied to and removed from the PCB. Additionally, in forming an electrical switch, a voltage applied to one or more actuating elements may be used to provide mechanical pressure to a composite material that is disposed between two conductive members. Application of a sufficient voltage allows for portions of the composite material to transition from an insulator to a conductor for providing an electrical pathway.

Abstract: In an embodiment, an apparatus includes a determiner, converter, adapter, and modifier. The determiner is configured to generate a representation of a difference between a first frequency at which a first signal is sampled and a second frequency at which a second signal is sampled, and the converter is configured to generate a second sample of the first signal at a second time in response to the representation and a first sample of the first signal at a first time. The adapter is configured to generate a sample of a modifier signal in response to the second sample of the first signal, and the modifier is configured to generate a modified sample of the second signal in response to a sample of the second signal and the sample of the modifier signal. For example, such an apparatus may be able to reduce the magnitude of an echo signal in a system having an audio pickup (e.g., a microphone) near an audio output (e.g., a speaker).
