Abstract: A modular connector with components that can be economically assembled to provide high signal integrity in a harsh environment. The connector includes an insulative housing bounding a mating interface, a conductive housing engaging a rear of the insulative housing and having tubes extending through the rear of the insulative housing to the mating interface, and lead assemblies disposed in respective tubes. The conductive housing has a channel extending from its top to its front.

A member is disposed in the channel and has opposite ends disposed in the top extension and locking feature of the insulative housing, respectively. Such a configuration prevents relative movement of components within the connector in a harsh environment and therefore provide more consistent signal paths.

Abstract: The present invention provides a method for equivalent high sampling rate FIR filtering based on FPGA, first, the coefficients h(k) of FIR filter are found by using MATLAB, multiplied by an integer and then rounded for the purpose that the rounded coefficients h(k) can be directly used into a FPGA, then the ADC's output of high data rate fs is lowered by dividing the ADC's output x(n) into M parallel data streams xi(n) of low data rate, and the M×L samples in one clock cycle is obtained by delaying the M parallel data streams xi(n) simultaneously by 1, 2, . . . , L? periods of the synchronous clock, at last, the samples yi(n) of FIR filtering output is calculated according to the samples selected from the M×L samples, and the filtered data y(n) of data rate fs is obtained by putting the samples yi(n) together in ascending order of i. Thus, the continuous FIR filtering of an ADC's output sampled with high sampling rate is realized, while the data rates before and after the FIR filtering are unchanged.
