PURPOSE:To execute easily a desired frequency modulation by storing an input/ output instruction and an internal operating instruction or the like to a memory, reading the instructions by a control means and conducting actual control according to the instructions. CONSTITUTION:A digital signal from an electronic computer or the like is inputted via an input means 9. A control means 10 controls the entire system and gives a command to an address generating means 14 so as to read a desired instruction from the stored instructions. When the read instruction is inputted to the control means 10 via an instruction decoding means 12, the control means 10 is operated in a manner according to the read instruction. Thus, the control means 10 discriminates a signal from the input means 9 according to the stored instruction in the storage means 13 and gives an output to an output means 11. Thus, the frequency is selected optionally and the devic with high stability is constituted. |
