The program CHIRP.EXE allows to calculate chirp signals and outputs them in vaious formats (including ascii and binary)
Some hints for the use with the ILO machine (ILO 88 or ILO 92): choose ilo-linear or ilo-nonlinear as output format
The program GNUPLOT.EXE can display the chirp signals. GNUPLOT was programmed by the free software foundation. CHIRP.EXE can create a suitable file GNU for the use of GNUPLOT. To display the chirp signals and their spectra, you can simply type GNUPLOT GNU. A second possibility is to start GNUPLOT and type load 'gnu' within GNUPLOT. Type help withing GNUPLOT to find out about GNUPLOT. If help does not work, set the environment variabel GNUHELP to the path of the file GNUPLOT.GIH.
