Abstract: There are provided an information transmitter and an apparatus including the same. The information transmitter includes a signal generator configured to output an information signal including pulses changed from a first state to a second state or a third state and subsequently changed from the second state or the third state to the first state. A time period in which some of the pulses are changed from the first state to the second state or the third state may be shorter than a time period in which some of the pulses are changed from the second state or the third state to the first state. The information transmitter also includes a transmitting coil configured to receive the information signal and generate a magnetic field based on the information signal.
