1. A system for transmitting medical data, comprising:

  • at least two electrodes to be placed on a body of a patient for generating an electrical signal;

    a first unit for receiving the electrical signal from the at least two electrodes and for differential amplification and band-pass filtering of the electrical signal to reject a common mode;

    a second unit for receiving the electrical signal differentially amplified and band-pass filtered from the first unit and for selectively rejecting a frequency of a sector and harmonics of the sector of the electrical signal, to generate an electrical transmission signal; and

    a modulator for receiving the electrical transmission signal from the second unit and for modulating the electrical transmission signal by a transmission frequency carrier; and

    an antenna for transmitting the modulated electrical transmission signal.
