1. A component comprising:

  • a semiconductor chip;

    a processor within the chip; and

    a transmitter circuit within the chip, the transmitter circuit being coupled to the processor to accept a digital input signal including a plurality of digital values from the processor, the transmitter circuit being operable to send an output signal including a series of signal levels representing the digital values and to emphasize high frequency components of the output signal relative to low frequency components of the output signal so that;

    (i) an output bit signal of the output signal representing a particular bit value has one signal level when the bit value is the same as a bit value represented by a predetermined preceding output bit signal; and

    (ii) the output bit signal representing the particular bit value has another signal level when the bit value is different from the bit value represented by the predetermined preceding output bit signal.
