Abstract
A non-linear type digital-to-analog converter comprising a decoder, control switching circuits controlled respectively by the outputs of the decoder, and an exponential function generating circuit whose analog outputs are selectively produced by the operation of the control switching circuits. An input digital representation is converted to an analog voltage output which is exponentially related to the input.
