  1. Final Part 2 Presentation Winter 2009 Mixed Signal Experiment Students: Alexander Kinko Roni Lavi Instructor: Inna Rivkin Duration: 1 Semester

  2. 3 Digital Experiments 3 Analog Experiments M.S.S Experiment A little reminder … Mixed Signal System (M.S.S.)

  3. Main Goal Giving the students in E.E. lab 1 a tool for a deeper understanding, designing and implementing of modern signal processing systems

  4. Project Overview • Foundations • Designing and manufacturing • a sample & reconstruction card • Designing and manufacturing an • audio interface card to M.S.S. card • VHDL M.S.S. core

  5. M.S.S. Platform (general block diagram) E.A.R. Card Pre-Amp M.S.S. Card E.A.R. Card Filtering DE2

  6. Basic Block Diagram of M.S.S. Platform Analog signals Analog signals Digital Processing Unit LPF/ HPF D/A D/A D/A D/A Digital Interface Optional Matrix DACs_Inteface LPF/ HPF ADC_Interface A/D Mic. Preamp Audio Interface Card DE2 Sampling & Reconstruction Card Analog signal Analog signal

  7. VHDL - M.S.S. Core ADC Interface PDAC Interface Inputs Outputs SDAC Interface Controls

  8. M.S.S. Experiment Contents • Developing experiments for the 7th experiment • Inverting Amplifier • Half-way Rectifier • Full-way Rectifier • Signal Generator Digital Recording

  9. Platform Introduction (basic mode) Analog signal (after digital & analog processing) Scope DE2 + M.S.S. Card Function Generator Matrix Analog signal (before processing) User Control

  10. M.S.S. Experiment Contents (cont.) • Developing experiments for the 7th experiment • Digital Audio Recording

  11. Platform Introduction (audio processing mode) DE2 + M.S.S. Card Analog signal (after digital processing) Analog signal (before processing) Scope User #1 Analog signal (before processing) Phones Phones Mic. Mic. Mic. Pre-amp Unit User #2 User Control

  12. Experiment Booklet Contents • Part 1 • Theoretical background • M.S.S. platform description • Preparation report • Experiment flow • Final report • Mini-project briefing

  13. Experiment Booklet Contents • Part 2 • Preparation report • Example of mini-project implementation • Mini-project implementation • Mini-project presentation

  14. Platform Introduction (project mode) DE2 + M.S.S. Card Analog signal (after digital & analog processing) Scope User #1 Analog signal (before processing) Phones Optional Matrix Mic. Analog signal (before processing) User #2 Mic. Pre-amp Unit Phones User Control MP3/4 Player User keyboard

  15. Products • M.S.S. platform • Experiment booklet • VHDL files for M.S.S. experiments • Built-In Self Test (B.I.T.)  • Production Files

  16. Testing of Products • Pre-pilot experiment • Two students who’s taking LAB 1 now (Tuchman Bros.) • Up to three weeks from now • Pilot experiment • Will take place in summer semester – to be scheduled • List of potential students – done • Reward for pilot students – to be determined • New experiment in the LAB 1 • Starting upcoming winter semester
