摘要： A method for transmitting a signal with a signal transmission rate selected from a plurality of signal transmission rates applicable to a facsimile transmission system. The distortion amount of a distortion measurement signal transmitted from a transmitting equipment is measured at a receiving equipment on the basis of the variation in the received distortion measurement signal. The distortion allowance range to which the measured distortion amount belongs is decided on the basis of the result of the measurement of the distortion amount. The transmission of the working signals is carried out with a transmission rate corresponding to the result of the decision of the distortion allowance range.
