Discrete Signals and Systems II - TRANSFORMS, WINDOWS, MODULATION: READ ME FIRST VERSION 1.01 To All Users: This disk is delivered with the version of the System Folder; System (v2.0) and Finder (v4.1). To replace the System Folder, startup your Macintosh with another disk "containing" System (v2.0) and Finder (v4.1), eject that disk (unless you have an external drive), insert a copy of this disk and then drag the icons of the System and Finder from the startup disk onto your copy. Transforms, Windows, Modulation will NOT operate on a 128K Macintosh. If you wish to use this product with newer versions of the System Folder, the screen will not refresh properly when the File Menu is used. The TWM Data Folder must be on the same disk as Transforms, Windows, Modulation otherwise, a "File Error" will occur when the application is started and the program may crash if you proceed. The TWM Data Folder contains the "TWM Image Folder" and the "TWM Scrap Folder." The images necessary for the operation of the program are stored in the TWM Image Folder. TWM Scrap Folder saves signals stored in 'storage bins.' Do NOT remove scrap #0 or screen save signal documents from the TWM Scrap Folder. TWM v1.01 can run on SCSI hard drives. It is recommended that on an HFS device, TWM 1.01 and all the related data/image files (scrap#0, screen save, saw, THEwindowER, POS) included on the disk be at the same level, i.e. in the same folder or all at the root level. If the files are scattered over the volume at different levels, the program will ask the location of each file at the start of the program. Also, TWM 1.01 is not recommended for a Mac SE or a Mac II; erratic behavior in signal file operations may result. Make sure the Discrete Signals and Systems disk is unlocked otherwise, a "File Error" will occur when you attempt to store a signal in a Storage bin. The Discrete Signals and Systems disk MUST be in the internal or external drive and do not operate the program after ejecting the disk. Due to a limitation in the graphics routines and screen resolution, discrete data values may appear unevenly spaced when the display width exceeds 60 points. Furthermore, when an array is all negative, the tick marks may overlap. In the "Point by Point" mode, if the value entered falls beyond the specified boundaries, lines may be drawn over the scroll bar. All standard Apple Desk Accessories are operational. However, if a desk accessory is moved around on the screen, the screen will not refresh until the accessory is put away. If infinite (INF) numbers are created during an operation, clear the signal in the graph window and then proceed. If vertical lines appear on the screen, save all signals, exit the program and restart. INF values may occur when using the exponential function generator or the exponential operation, if the base and/or the exponent are not carefully sel…
