Toshiba IR Test Apparatus Project Nurfazlina Kamaruddin Ahmad Nazri Fadzal Zamir Izam Wan Othman

Completed task  Met with Toshiba  Verified LabVIEW can detect signal  Proposed 5 different tasks for the project

Recap meeting with Toshiba  Will get documentation from Toshiba  After receiving the documentation, will create library using LabView  Discovered problem with our system (i.e. TOSHIBA TV)

Revised Project Tasks  Replicate Measurement  Build simulator/ emulator in LABVIEW  Create Library for 3 brands of DVD and VCR  Obtained square wave signal generated by function generator with LABVIEW

Measurement using LabVIEW  Used function generator to produce square wave signals ( frequency : 40kHz )  Captured square wave signals using Measurement & Automation Explorer (DAQ software)  LabVIEW retrieved signals from MAX
