The latest revision of the standard for connecting business machines with serial interfaces is known as RS-232-D or, technically EIA 232-D. Seyer's authoritative guidebook on the RS-232 interface has been completely updated, with charts showing how to connect some 1,000 devices. Written in layman's terms, it requires no prior knowledge of the subject. Annotation copyrighted by Book News, Inc., Portland, OR

This text presents readers with an engaging while rigorous manual on the use of oscilloscopes in laboratory and field settings. It describes procedures for measuring and displaying waveforms, gives examples of how this information can be used for repairing malfunctioning equipment and developing new designs, and explains steps for debugging pre-production prototypes. The book begins by examining how the oscilloscope displays electrical energy as traces on X and Y co-ordinates, freely transitioning without loss of information between time and frequency domains, in accordance with the Fourier Transform and its modern correlate, the Fast Fourier Transform. The book continues with practical applications and case studies, describes how oscilloscopes are used in diagnosing pulse width modulation (PWM) problems--looking at serial data streaming and analyzing power supply noise and premises power quality issues—and emphasizes the great functionality of mixed-signal as opposed to mixed-domain oscilloscope, and earlier instruments. Featuring many descriptions of applications in applied science and physics, Oscilloscopes: A Manual for Students, Engineers, and Scientists is ideal for students, faculty, and practitioners.
