Coad and Yourdon suggested _______________ selection characteristics that should be used as an analyst considers each potential object for inclusion in the requirement analysis model ? Q5. View Answer, 4. C. Linear variable differential transformer (LVDT) D. Photodiode. Because the device relies on the coupling of magnetic flux, an LVDT can have infinite resolution. var hs = document.createElement('script'); hs.type = 'text/javascript'; hs.async = true; How does the value of mutual inductance vary between two coils of an inductive transducer? Which of the following is not a diagram studied in Requirement Analysis ? b) Passive transducer a) Self inductance b) Mutual inductance c) Reluctance d) Permanence. d) Sensitivity is equal to scale factor These short solved questions or quizzes are provided by Gkseries. (B) Resistance (X) A Linear Variable Differential Transformer (LVDT) is a displacement transducer, used to measure displacement, based on the effect of the mutual inductances. Thus a strain gauge, an LVDT, a thermocouple or a thermistors may be called analog transducer, as they give an output which is a continuous function of time.
