the signal transferred from the second terminal may be fully restored the restored signal is provided as an output signal dout 1 according to the above describe configuration the data transmitting and receiving apparatus 200 may perform interactive data communication through one channel thus the data transmitting and receiving apparatus 200 may realize a relatively high data transfer rate and effective bandwidth next there is provided a data transmitting and receiving apparatus in which an inductor of fig7 is replaced with a lower cost resistor reference is made to fig8 which is a circuit diagram of a data transmitting and receiving apparatus 300 according to still another embodiment of the inventive concept the data transmitting and receiving apparatus 300 includes a first terminal and a second terminal the first terminal of this example includes a first coil l 1 a first flip flop 310 a a first driver 320 a a first replica driver 330 a a first compensator 340 a a first subtractor 350 a and a first hysteresis comparator 360 a similarly the second terminal of this example includes a second coil l 2 a second flip flop 310 b a second driver 320 b a second replica driver 330 b a second compensator 340 b a second subtractor 350 b and a second hysteresis comparator 360 b the first terminal and the second terminal are substantially identical in configuration and operation therefore this embodiment will be described with respect to the first terminal only in this embodiment a compensator resistor r 1 is used as the first compensator 340 a when the input signal din 1 is received to the first flip flop 310 a the first flip flop 310 a buffers the input signal din 1 and outputs the.
