Definitions

  • the word transducer is used to mean a device made of material which, when a pulse of electrical energy is applied thereto is capable of transforming the electrical energy into mechanical energy. Conversely, when mechanical energy is applied thereto, it possesses the ability of being able to transform the mechanical energy into a pulse of electrical energy.
  • Equation 1 Since the capacitance of each transducer is approximately equal we may then write the Equation 1 as:
