Abstract
Abstract A voltage divider network with means for selectively and sequentially interconnecting resistors of various ohmic values in one leg thereof to provide discrete voltages, each one of which voltage is associated with a corresponding resistor value. The discrete voltage levels are detected and converted to a binary coded output in accordance with an intelligible encoding of the resistors. For such encoding the different resistor values and discrete voltage steps used are equal in number to the binary code which is to be generated. For example, for a binary code of 2 to the second power (22), 4 resistors are selectively insertable in the voltage divider network and four different voltage levels detected. For a binary code of 2 to the fourth power (24), 16 resistance values and voltage levels are utilized. In order to minimize the number of different resistance values and voltage levels needed for a given binary code level, more than one voltage divider with its associated resistors and voltage level detectors may be utilized and ''''read'''' simultaneously.
