摘要： A method of estimating a change of a variable over a measurement window, comprising the steps of taking multiple samples of the variable during the measurement window, defining a weight to be associated with each sample, the weight varying as a function of position of the sample within the measurement window, processing the samples taking account of their weight to form an estimate of the change in the variable.

摘要： Various examples are directed to configuring a configurable hardware module to perform a measurement of a physical quantity. A configuration manager may receive an indication of the physical quantity and performance factor data describing the measurement of the physical quantity. The configuration manager may generate a hardware configuration of the hardware based at least in part on the indication of the physical quantity and the performance factor data. The hardware configuration may comprise instruction data to configure the hardware module to execute a dynamic measurement of the physical quantity. The configuration manager may also generate configuration data describing the hardware configuration, wherein the configuration data comprises simulation data comprising input parameters for a simulation of the hardware configuration and hardware configuration data for configuring a hardware module to implement at least a portion of the hardware configuration.

摘要： An analog multiplexer may be used for sampling an input voltage that is capable of having a higher voltage level than an upper supply voltage. The analog multiplexer includes a plurality of input switch circuits and a shorting switch circuit. The plurality of input switch circuits include n-type or p-type laterally diffused field effect transistors (NLDFETs or PLDFETs). At least one of the input switch circuits includes a level shifting switch circuit that is able to sample an input voltage that is greater than the upper supply voltage for the multiplexer. A shorting switch circuit, at an output of the multiplexer, includes a capacitively coupled gate drive circuit and is configured to short a first differential output to a second differential output after the input voltage is sampled.

摘要： An interface system between an RDC and a connected resolver dynamically matches an input range of the RDC to the output range of the resolver's output signals. The interface system may include methods and/or apparatuses to determine the amplitude of sinusoidal input signals presented to the RDC by the resolver and to compare the amplitude against high and low threshold values. A gain control signal may be generated, which may be corrected if the detected amplitude either exceeds the high threshold or falls below the low threshold. The gain control signal may be output to a circuit in the RDC or in the resolver that corrects any mismatch that occurs between the RDC input and the resolver output. For example, the gain control signal may control the amplitude of an excitation signal applied to a primary of the resolver or the gain control signal may be applied to an analog to digital converter at the input of the RDC to control its effective input range.

摘要： A serial protocol and interface for data transmission from a data transmitter 12 to a data receiver 14 where the propagation delay may be up to several clock cycles long and may be varying slowly. The data receiver provides a clock to the data transmitter. A synchronization signal provided by either the receiver or the transmitter initiates a frame of data transmission at a transfer rate controlled by the clock. The synchronization signal coordinates the transmission of a data header followed by a predetermined number of data bits, known as the frame length. The data receiver uses the header bits to determine the times to sample the subsequent data bits. The length of the frame is limited to provide sufficient likelihood the propagation delay line characteristics have not changed enough to cause a bit error. The system resynchronizes at the beginning of each frame.
