The document discusses several topics related to automated testing, data analysis, and digital signal processing: - It describes a Visual Basic script for automating control and measurement in a probe station, including initializing instruments, performing measurements, and saving data. - It mentions using Perl scripts for mining and organizing serial data from post-measurement files. - It provides an overview of a Max/MSP patch for a digital effects processor that can implement various audio effects through algorithms incorporating techniques like phase distortion and time delay.

2. Automated Test Scripting with Visual Basic Mining Serial Data with Perl Scripts Schematics, Soldering & Circuit Board Control Systems DSP Audio Effects Texas Instruments - MatLab/Simulink Max/MSP

3. For Use in Automated Control of Probe Station Features: Custom GUI Updatable Data Entry Fields Saves Time User Friendly Script Easily Modified

4. Declare Variables Sub Routines Initialize Instrumentation Perform Measurements Buffer Measurement Data and Write to Spreadsheet Cells Index Site Coordinates Resume Testing at New Site Quit Testing

5. Uses: Mining Serial Data Organizing Post Measurement Data Data Analysis How it Works: Script reads in a file. Pattern matching operator (based on keyword) scans data. A new file is output with column headers, etc….as desired.

7. Demonstrates: Ability to solder Ability to work from a schematic Enclosure

10. Demonstrates: u-Controller Know How Programming Skill Peripheral interfacing Skill – Relays, Stepper Motors, Servo Motor control… … Prototyping Breadboard Skill

11. Novation Launchpad USB Peripheral Device Max4Live Device Features: One finger control for triggering chord structures within Ableton Live Works with Novation Launchpad All standard chord variations are possible Design is based on circle of fifths premise

12. Simply Drag & Drop Plug-in into Session Works just like a VST or Direct X plug-in

13. Arrows Indicate Encapsulated Subsystems

14. Chord Structures Auto Velocity Structure

16. Hardware TMS320C6713 DSK Windows PC Software: Matlab/Simulink Code Composer Studio Max/MSP

17. A switch case is used to select desired effects patch

18. Algorithms Incorporate Phase Distortion, Time Delay, Frequency Modulation, Amplitude Modulation, Filtering, Gain and Signal Feedback

19. Multi Effects Processor Firmware is stored in onboard flash ROM memory for boot loading

21. Second attempt at implementing a DSP based audio effects processor. This time with Max/MSP graphical programming environment.

22. Model realized with graphical programming. Model is implemented to run on Microsoft Windows or Mac PC. Requires Max 5, or Max Runtime (free) to deploy the patch.

23. Features: GUI FFT Spectrum Analysis

24. Ring Modulation / Tremolo Effect Description: Ring Modulation can be described as Frequency Modulation The Tremolo Effect is essentially Amplitude Modulation of Audio Signal
