摘要
The invention relates, inter alia, to an arrangement (10) for converting a first digital signal *Uh) with a first voltage swing into a second digital signal (Un) with a voltage swing which is smaller than the first voltage swing. The invention provides a threshold value detection device (30) which compares an input signal, which is applied to the input and corresponds to the first digital signal or has been formed with the latter, with a threshold value (Uref) and which if the input signal exceeds the threshold value- generates a pulse sequence (PI) comprising switch-on and switch off pulses. A DC isolation device (40) which is conneced to the output (A30) of the threshold value detection device (30) of the threshold value detection device (30) forwards the pulse sequence (PI), with potential isolation, to a signal recovery device (50) which generates the second digital signal using the pulse sequence (P2) which is applied to the signal out put (A50) of the DC isolation device.
