Data Acquisition Techniques Using Personal Computers by Howard Austerlitz

By Howard Austerlitz

Data Acquisition ideas utilizing own Computers includes the entire details required by means of a technical expert (engineer, scientist, technician) to enforce a PC-based acquisition procedure. together with either uncomplicated educational info in addition to a few complicated issues, this paintings is appropriate as a reference e-book for engineers or as a supplemental textual content for engineering scholars. It supplies the reader sufficient figuring out of the themes to enforce an information acquisition method in line with advertisement items. A reader can however the best way to customized construct or write his or her personal software program. that includes assorted info, this publication should be worthy to either the technical expert and the hobbyist.

Key Features
* includes tables of reference info on PC/XT/AT desktops which are often now not present in a unmarried source
* comprises info, similar to I/O addresses, reminiscence maps, and interrupts
* Discusses software program reference fabric together with BIOS and DOS interrupt calls
* offers worthy interface details together with timing diagrams, layout examples, and outlines of ordinary interfaces, similar to the RS-232 serial interface

Hieroglyphs: A Very Short Introduction (Very Short Introductions)

Hieroglyphs have been excess of a language. They have been an omnipresent and omnipotent strength in speaking the messages of old Egyptian tradition for over 3 thousand years. This historical kind of expression was once used as paintings, as a method of selecting Egyptian-ness, even for verbal exchange with the gods.

T h e r e are some problems using diodes in log amplifiers. T h e y are very t e m p e r a t u r e sensitive, since the forward voltage drop across a diode is a function of t e m p e r a t u r e . In fact, this property is often exploited in Figure 3-20 Simple logarithmic amplifier. 3 Analog Conditioning Circuits 39 INPUT 1 — OUTPUT = INPUT 1 χ INPUT 2 INPUT 2 Figure 3-21 Analog multiplier. diode t e m p e r a t u r e s e n s o r s . A l s o , the signal range over which the diode has a logarithmic r e s p o n s e is s o m e w h a t limited.

This value is actually a percentage of the full-scale reading, but it is c o m m o n l y specified as the n u m b e r of output bits. An «-bit n A D C has 2 possible output values and a resolution of 1 part in 2". F o r e x a m p l e , a 10-bit A D C has a resolution of approximately 0 . 1 % (1/1024). High resolution (more bits) is usually desirable in an A D C . N o t e that an A D C ' s a c c u r a c y can be no better than its resolution, for an individual reading. ADC Sampling Rate Sampling or conversion rate is the A D C specification most often e x a m i n e d .

ADC Accuracy A n o t h e r important A D C characteristic is its absolute accuracy, which is the m e a s u r e of all error s o u r c e s . This is sometimes referred to as the total unadjusted error. , ± 1 L S B ) . It is possible for a c o n v e r t e r ' s absolute a c c u r a c y to be better than its resolution. By definition, a c o n v e r t e r ' s resolution is 1 L S B .
