Q. The figure-2 depicts digital sensor operation. The following setup uses a light sensor to measure the speed and produces a digital signal. Typical conversion speed of ADC is _____ a) Less than 1µs b) Less than 100 µs c) Less than 500 µs d) Greater than 1000 µs View Answer The light sensor captures the presence or absence of the light and sends logic 1 or logic 0 signal accordingly to the counter. A transducer is an electronic device that converts energy from one form to another. The transducer is of many types, and they can be classified by the following criteria. Common examples include microphones, loudspeakers, thermometers, position and pressure sensors, and antenna.Although not generally thought of as transducers, photocells, LEDs (light-emitting diodes), and even common light bulbs are transducers. Interface. answer choices … Example of digital transducer is a Shaft Encoder, Limit Switch, Digital Tachometer etc. These pulses are counted by the counter and final output is displayed on the numeric display. Shaft Encoder is used to measure the angular position & velocity and its output is digital in nature. that will provide a change of 0.1V on the voltmeter is the resolution of the sensor/voltmeter system. Reduce the acoustic impedance mismatch between the element and tissue. 1. Control element. Function of transducer is to convert A. Let us consider the non-electrical quantities such as pressure, illumination of light and temperature. There are different types of digital sensors that overcome disadvantages of analog sensors. In digital sensors, the signal measured is directly converted into digital signal output inside the digital sensor itself. Which of the following is a digital transducer? Active transducer is a transducer, which converts the non-electrical quantity into an electrical quantity. Non electrical quantity into electrical signal C. Electrical signal into mechanical quantity D. All of these View Answer / … as a primary and secondary transducer; as a passive and active transducer; as analogue and digital transducer; as the transducer and inverse transducer; The transducer receives the measurand and gives a … The shape corresponding to the image created by a phased array transducer most closely corresponds to which of the following? They produce an output signal in the form of some variation in resistance, capacitance or any other electrical parameter, which than has to be converted to an equivalent current or voltage signal. c) Digital transducer d) Pulse transducer Ans : (d) 4. Example of digital sensor: Digital Light sensor which uses rotating disc to generate output pulse with logic 0 and logic 1. Digital Accelerometers. The change in input (temperature, pressure, etc.) answer choices . What is the input of the data acquisition system (DAQ) to which a transducer is connected called? And this digital signal is transmitted through cable digitally. This set of Instrumentation Transducers Multiple Choice Questions & Answers (MCQs) focuses on “Analog to Digital Converters”. The matching layer between the piezoelectric element and the tissue is designed to: Transducers which require an external power source for their operation is called as a passive transducer. Transducer - MCQs with answers Q1. For example, a photocell (LDR) is a passive transducer … Limit Switch is the simplest example of digital transducer. Following is not an example of transducer. By transduction used. Channel. In the above setup, the rotating disc is connected to the shaft of a motor and has number of transparent slots. Hence, we will get the following three active transducers depending on the non-electrical quantity that we choose. Electrical signal into non electrical quantity B. • In digital systems generally , resolution may be specified as 1/ 2 N (N is the number … Through cable digitally and its output is digital in nature and final output is digital in nature high.
