Abstract:
A transmitting circuit has a first transmitter configured to generate a first electric pulse signal in synchronization with a rising edge of a digital electric input signal, a second transmitter configured to generate a second electric pulse signal in synchronization with a falling edge of the digital electric input signal, a first variable impedance circuit configured to supply a bias current to a first light-emitting element only for a predetermined period before the first light-emitting element for converting the first electric pulse signal into a first light signal is supplied with the first electric pulse signal, and a second variable impedance circuit configured to supply a bias current to a second light-emitting element only for a predetermined period before the second light-emitting element for converting the second electric pulse signal into a second light signal is supplied with the second electric pulse signal.
