PURPOSE:To make it possible to supply a signal suitable to characteristics of a load circuit by storing a memory with digital data that correspond to desired output voltage characteristics. CONSTITUTION:With an address signal from address sinal generator 1, programmabld read-only memory PROM2 is read from address 0 to address (n). Then, digital data 0-N read out of this PROM2 are inputted to and converted by digital- analog converter 3 into analog data, so that an output voltage ranging from 0-NV will be developed at output terminal 4. For this purpose, random data 1-N are set as data written in PROM2, so that a voltage signal of desired output voltage characteristics of 1-NV can be obtained from the output terminal. |
