SCIENZE PROPEDEUTICHE

Module MISURE ELETTRICHE ED ELETTRONICHE

The specific training objectives are functional to the professional figure that the course intends to train and gives competencies  in the field of  electrical and electronics measurements, sensors and transduction elements inherent the field of audiometry.

In this context, the course aims to train technicians with a suitable basic scientific training and adequate competences of the general technical-scientific content on the basic of metrology and transducers in the audiometric field.

Knowledge and understanding

The student will acquire knowledge on metrology, measurement systems, sensors and transducers also in audiometric field. The main applications will be related to the fields of electronic engineering, polarized towards a professionalizing aspect in accordance with the Degree Course.

Applying knowledge and understanding

After Course completion,  students will have the necessary skills to perform measurements, with appropriate methodology and systems, identifying their main sections and functionalities.

Making judgements

Students will acquire autonomy of judgment for an accurate analysis of the systems considered.

Communication skills

The student will reinforce the technical language of measurement systems with the goal of being able to adequately present him/herself on the job market with adequate skills and an appropriate technical profile.

Learning skills

The student will be able to autonomously expand his knowledge of electrical and electronic measurements also through in-depth study of reference texts, on articles of specialized scientific journals.

  Oral test

  Learning assessment may also be carried out on line, should the conditions require it.

• To ensure equal opportunities and in compliance with current laws, interested students may request a personal interview in order to plan any compensatory and/or dispensatory measures based on educational objectives and specific needs. Students can also contact the CInAP (Centro per l’integrazione Attiva e Partecipata - Servizi per le Disabilità e/o i DSA) referring teacher within their department.
