Abstract:
1. A signal correction circuit for use in a signal transmitter apparatus that transmits a transmission signal generated in accordance with a clock signal having a predetermined cycle via a transmission line, the signal correction circuit comprising: a storage unit for storing a signal level of the transmission signal at a first timing of the clock signal, and outputting the signal level; a first detector for detecting the signal level of the transmission signal at a second timing subsequent to the first timing of the clock signal, detecting a first signal level difference between the detected signal level and the signal level from the storage unit, generating a first detection signal representing the detected first signal level difference, and outputting the first detection signal; and a delay device for delaying the transmission signal so as to keep a rise time of the transmission signal substantially within a predetermined value range by adding a capacitance corresponding to the first signal level difference to the transmission line based on the first detection signal.
