Definitions

  • voltage generator 10 is required to have a predetermined voltage characteristic having three sharply distinct sections of varying curvature, including a section of small slope, another section of medium slope, and a section having a large slope.
  • the apparatus 10 shown in FIGS. 1 to 3 for obtaining the required voltage characteristics includes a voltage source connected to terminal 30, variable resistors 32, 34, voltage divider 36, and ground terminal F.
  • the voltage divider 36 has a number of parallel connected potentiometers 38 to 43, and end terminals 44, 46.
  • Potentiometer 50 has end terminals 52, 54 connected to terminals 44, 46.
