  4.         Total Morse speed is dependant upon the CHARACTER SPEED, INTER-
  5. CHARACTER DELAY and INTER-WORD DELAY, to the PARIS test formula.  The
  6. variation of any one component  will affect the resulting WPM (words per
  7. minute) rate.  Morse is composed of Dits, Dahs and time delay to the ratio
  8. of:
  9.  
  10.        DIT                                 = 1 UNIT
  11.        INTER DIT/DAH SPACE                 = 1 DIT
  12.        DAH                                 = 3 * DIT
  13.        INTER-CHARACTER DELAY               = 3 * DIT
  14.        INTER-WORD DELAY                    = 7 * DIT
  15.  
  16.  
  17.     Within the program the Inter-Character delay is multiplied by 3,
  18. while the Inter-Word delay is Multiplied by 7.  For realistic morse
  19. sounding when the SYMBOL SPEED is greater than total morse speed, the
  20. ratio of (3 * INTER-CHARACTER DELAY) / (7 * INTER-WORD DELAY) should be
  21. in the range of 0.4 to 0.7.
