Providing clear and easily understood explanations without sacrificing depth and completeness of presentation, Digital Measurement Techniques, Second Edition explores the basic principles of electronic instrumentation. The First Edition filled the need for a comprehensive text on the subject. Completely revised and updated to include the latest techniques and instruments, the Second Edition takes its place as a standard text. Throughout the text, illustrative examples are provided to help students understand the theory and design philosophy. At the end of each chapter a set of problems is offered to help students develop their skill in using the theory. See what's new in the Second Edition: Software-controlled measurements Time interval measurement when the two events occur arbitrarily, and to indicate the order of occurrence, and a practical set up for the time interval measurement Micro-controller based phase meter and multi-phase sequence indicator Decibel meter Input circuitry of a frequency counter Measurement of low-frequencies in a narrow band Basics of ac bridges Quality and dissipation factor measurement by phase compensation technique Impedance measurement in the Cartesian coordinates formResistance Ra is adjusted until the currents Ix and Is in the two parallel branches come in phase. Under this condition, the phase angles of the two branches are equal, i.e., tan~l(l/uCxRx) = tan-l(l/Alq, J?, ) or l/uCIRx = l/uCsRs or tan 6x a€” tan Asa . ... Then measure the ratio of the voltages across Ca and Rs. 7.3.5 The tan-5 meter (for an equivalent parallel RC circuit) The above methods are applicable to findanbsp;...
