Digital technique for the simultaneous measurement of velocity and temperature
Review of Scientific Instruments, 1978A computer-oriented, hot-wire anemometer technique for the simultaneous measurement of velocity and temperature in heated turbulent flows is described. This technique involves conversion of analogue anemometer voltage signals into digital forms and processing of these latter on a digital computer, in accordance with the anemometer response equations ...

Computerized digitizing technique for DLTS measurements
IEEE Transactions on Instrumentation and Measurement, 1994An enhanced version of an algorithm developed by Maguire and Marshall in their computerized DLTS system is presented. Improvements consist of introducing analysis of partial processing of digitized transients by deleting the initial part, which usually includes the loading transient caused by the measurement circuit RC constant.

Digital bus faults measuring techniques
Proceedings International Test Conference 1998 (IEEE Cat. No.98CH36270), 2002This paper describes techniques available today to detect digital bus faults on electronic PCB's using in-circuit testers. The paper will also suggest a new test technique called "CLIPS" developed using a Teradyne Z1890 ICT tester. The CLIPS uses a vector technique in which dynamic pulses are applied to the bus lines at high speed.

Digital techniques for laboratory measurements
American Journal of Physics, 1975The development of measuring equipment in modular form with digital readout is described. This equipment is adapted to the measurement of many physical quantities such as velocity, frequency, temperature, resistance, capacitance, etc. It is easier to use, faster, and more precise than conventional equipment and forms a firm basis for more advanced work.

Digital lock-in technique for measurement of polarization of radiation
Optics Letters, 1977A highly versatile polarimeter has been constructed for determining all the Stokes parameters for a beam of radiation. Polarization measurements are performed using digital lock-in techniques by replacing the linear retardation plate with an electro-optic crystal, which can be externally modulated.

A technique for real-time digital measurements in laparoscopic surgery
Surgical Endoscopy, 2004The current techniques for the measurement of intracorporeal targets in laparoscopic surgery are relatively cumbersome and imprecise.A structured light technique was used to obtain the length and width of two defects and an object in a laparoscopic training box.

Nonlinearity Measurement of a Voltage Ramp Using a Digital Technique
Journal of Circuits, Systems and Computers, 2017The paper presents the idea and implementation of a digital nonlinearity measurement of a voltage ramp. The measurement process is based on evaluation of a time period between the moments when an input voltage ramp and an ideal voltage ramp reach the given value. During this period, the clock pulse train is supplied to the counter.

A Non-Enumerative Technique for Measuring Path Correlation in Digital Circuits
Journal of Electronic Testing, 2012The correlation between the physical paths of a digital circuit has important implications in various design automation problems, such as timing analysis, test generation and diagnosis. When considering the complexity and tight timing constraints of modern circuits, this correlation affects both the design process and the testing approaches followed in

Digital recording techniques for electrical insulation measurements
IEEE Electrical Insulation Magazine, 1989The problems of measuring the characteristics of transient voltage and current waveforms occurring in high-voltage power systems are discussed, and the analog recorders that have been used in the past are reviewed. The theory of operation of digital recorders is described, and sources of recording errors are examined.
