    Digitized Signals

    All the time-domain signals appearing on this page (under EE419 and EE515) are in the audio range. These were digitized with a sampling rate of 22255Hz. These signals are in Ascii format, and can be input directly into MatLab or DaDisp. Notes are available on performing I/O with these signals, changing formats (like to .wav) and spectral analysis.

  55. HP Info for Educators

    DaDisp Software Package

    DaDisp is a graphical package that is very useful for generating signals and examining their transforms in the frequency domain. It is used extensively in the EE459 Lab. The student version is available at no charge.

    The student version must be augmented for use in EE459. This requires three additional files:

  56. dadisp.mac
  57. dadisp.spl
  58. nahvi.mac

    Macro files are available in lab. Bring a floppy to make you own copy, and then 'Use at your own risk.'

    To install these files, place 'dadisp.*' in the main DaDisp2k directory, then place 'nahvi.mac' the DaDisp2k\macros directory.

    If you experience problems setting up DaDisp to automatically load the macros, they can be manually loaded, use the menu option: Tools->Macros->ReadMacros

    Suggestion for DaDisp: Save your work on a floppy, so that you can move from machine to machine, or between CalPoly and home. To start working off of a floppy, first change directory (File -> Change Directory and select the a: drive). Then create a new LabBook (also under file menu) and create a new worksheet.
