In electronics, a device that coverts energy from one form to some other form is known as a transducer. For example, a loudspeaker converts electrical energy into sound, hence it is a transducer. Another common examples of transducers include microphone, thermometer, pressure sensor, antenna and other position sensors, etc. Based on excitation system, transducers are broadly classified into the following two types namely, Active Transducer Passive Transducer The most fundamental difference between active and passive transducer is that an active transducer does not need any external power supply to generate output, whereas a passive transducer needs an additional ...
