Corso di Elaborazione Numerica dei Segnali  (6 CFU)  per  l’AA  2016-2017

Obiettivi 
Il corso ha l’obiettivo di fornire fondamenti e strumenti metodologici per analizzare con  tecniche numeriche Segnali e Sistemi utilizzati nei modelli e nei casi d’uso presenti nelle discipline afferenti a Scienze e Ingegneria dell’Informazione, Elettronica, Telecomunicazioni, Automazione, Biomedicina, Meccanica dei Sistemi Vibranti, Ambiente e Territorio, Fenomeni Sismici.
Nel percorso di "Telecomunicazioni" l'esame di "Teoria dei Segnali" è propedeutico a quello di "Elaborazione Numerica dei Segnali".
Ai fini di una agevole comprensione degli argomenti trattati e di un buon utilizzo degli strumenti richiesti si ritengono acquisite le conoscenze relative a:
- Fondamenti di probabilità
- Analisi di segnali e sistemi nel dominio del tempo e della frequenza
- Fondamenti di programmazione

Contenuti
Richiami su segnali e sistemi a tempo discreto.
Sequenze e segnali numerici.
Conversione analogico/numerica: campionamento e quantizzazione, ricostruzione del segnale analogico a partire dai suoi campioni, sottocampionamento e sovracampionamento.

Gennaro REPPUCCI    curriculum vitae

Born in Naples, on the 25^th May 1949,  he achieved the  Maturità Classica degree (4^th Level of EQF) in 1967.  He graduated with honours in Electronics at Federico II University in Naples in 1974,  winning Telespazio "P. FANTI" 1974  award.  In the same year he attained his Professional Government License  with the highest rank.

In the year 1975 he served as lieutenant c/o  Italian Anti  Aircraft Artillery School  in   Sabaudia (LT, Italy),  being  in charge as  40/70 Fire Unit Commander.

In 1975 he was appointed by the Italian Public Education Ministry  as Research Worker with the “Federico II” Naples University, where from  1975 to 1977 he worked with the Italian Research Council (CNR) Telecommunication and Information Theory Group and supported Electrical Communications  and Radio Communications courses. 

From 1977 to 1978 he worked with the R&D department of a shipyard company and was in charge for Electrical & Electronic Equipments for Fast Fibreglass Planning Boats, including On Board Energy Management as well as Navigation Aids,  VOR/DME, DECCA, LORAN  and Collision Avoidance Radar Systems. In that framework he developed a microprocessor based Command & Control System for a 65 feet fast boat.     

In the year 1978 he joined Radar System Division of Selenia SpA working for the Product Engineering Dept. . From 1983 until early 1985 he attended the "Engineering Management" courses held by ISSEL in  Rome.

From 1985 he was in charge for Signal & Data Processing Dept  of Alenia Marconi Systems (AMS, formerly Selenia) Engineering and Technology Division.

He was involved 15 years long in Equipment/Instrumentation/IPR, Algorithms, Architectures and Systems for Signal/Data processing as well as in the development of HW, FW and SW solutions, requiring special tools for Software development as well as for Logical & Physical design of  ASIC devices.

He  was involved in the development of Radar Systems for the Italian Air Force (AMI), for the Italian Navy (MMI), for the Italian Flight Aid Organization (ENAV), for the US NAVY, for the German  Flight Organization, for the Pakistan Navy, for the Brazilian Navy.

On May of 1999 he attended the course on Business Excellence Model (BEM) held by professor  TRONCI from “La Sapienza” Rome University, and was appointed BEM Assessor of AMS  Radar System Division.

From 1994 to 1997 he was appointed as Lecturer in “Electrical Communications” by “Federico II” Naples University, and the same he was for the academic year 1994/1995 by Fisciano/Salerno University.

In the year 2000 he joined the R&D Group of Uni.Com SpA, where he was in charge as Technical Director for the design and development of

              o              Fixed Cellular Telephony devices and GSM based Telemetry Systems (M2M segment)

              o              Digital Video Broadcasting (DVB) Receivers Decoders, for DVB-x (C-S-T) networks

              o              Home Networking Devices and Systems, both Power Line and WiFi (802.11x) 

              o              Remote Video Surveillance  and Control Systems

              o              Custom Embedded Systems/Controllers  for Home Appliances
