Digital transmission circuit |
摘要 |
A digital transmission circuit for processing and outputting a digital output signal includes a mark density detecting circuit for detecting the amplitude of the DC signal component of the digital signal and a DC level shifter superposing a DC signal component on the digital signal in response to the detected amplitude. Thereby, the output signal level, regardless of the mark density of the input signal, does not drift.
