This book represents a substantial revision of the first edition. The authors have greatly reduced the treatment of semiconductors and increased the coverage of operational amplifiers. The shift in emphasis from discrete to integrated devices enabled an improvement in organization. The experimental section has been expanded also. Consequently, although the cover and the number of pages is unchanged, there is a considerable difference between the two editions. Only the chapter on mathematical background is unchanged. As hefore, the authors intmduce the theory of instrumentation a t a reasonably sophisticated level for uooerclass or first . vear " erad"ate students. ~ a i c u l u is s assumed and they develop the Laplace transform, phasors, and complex representation of reactive circuits. In addition t o covering the topics of signals, passive components, operational amplifiers, power supply circuits, logic systems, and flip flops, there are chapters about transducers, analoe instrumentation. and analoddieital .. ,. cinwits A s in rhe first edlliun, an inslructwnnl .trt.~~+th of the book I; thr I r r ~ tnumt ber I".&, 1 1 yrr~~l,lemswith ;~,lu!um,, no! usr numerical answers, to all of them.
