Abstract
In a transmission signal correction circuit, a first output circuit outputs a data string to outside. A second output circuit for correction is connected in parallel with the first output circuit. The second output circuit receives the data string to add the data string to an output signal of the first output circuit during a period when a control signal is kept generated. A data string detection circuit generates the control signal when detecting a signal sequence, in the data string, that affects a transmission waveform.
