New design and manufacturing approaches reduce this DMM's costlperformance ratia and allow it to be calibrated electronically. Low-Cost and Portability Gome to Data Acquisition/Gontrol Products, by JamesJ. Ress-meyer You can take this inexpensive, battery-powered instrument into the f ield to monitor f low rates, wind velocities, bridge sfresses, soil temperatures, or whatever. Data Acquisition...

In this paper, error-control coding is used with a six-port direct-digital QPSK receiver [1] in an AWGN channel. The direct-conversion wideband six-port millimeter wave receiver proposed herein meets the needs of MMIC mass-market wireless communications. Convolutional code and Turbo code are used as the channel codes for the first time in this type of receiver. The BER results for the convoluti...

An information system has been designed for monitoring the quality of multiassortmental manufacturings of phosphorus – containing products substances. The information system is based on the international CALS standard (ISO-10303 STEP). It contains the following information for the main elements of analytical monitoring: a list of elements to be monitored (substance classifier), details of the a...
