Abstract

PURPOSE:To obtain a modulated signal containing a reduced DC component by adding a simple DC component eliminating process, thus ensuring a direct application of a modulated digital signal to a device having a magnetic coupling circuit. CONSTITUTION:The data signal A supplied from the input terminal 1 is converted into a code signal through the code circuit 2, and the converted output is supplied to the delay circuit 4 and the counter 3. The output of the counter 6 to which a modulated output is supplied plus the output of the counter 3 are supplied to the deciding circuit 7. A reverse signal is delivered from the circuit 7 under a specific condition and then applied to the inverting circuit 5. The code signal C is delivered from the circuit 5 and receives an NRZ modulation through a modulator to be turned into a modulated signal.
