摘要： A transmission line having a fixed characteristic impedance, e.g., 600 ohms, is coupled to a receiver through an input transformer working into a very small impedance, e.g., 10 ohms or less. As compared to a conventional arrangement, where an input transformer works into a load nearly as high as the characteristic impedance of the line, the new arrangement has considerably better low frequency response and delay distortion characteristics. The new arrangement permits a much smaller transformer to be used if desired while retaining favorable low frequency response and delay distortion characteristics.
