A multi-channel circuit for telemetering signals representing physiological values from a point in a human body to a receiver (24) outside of the body. The two signals (S.sub.1, S.sub.2) other than the temperature signal (27') are used to provide two frequency modulated signals (14, 16) summed by an ...
