Abstract
A signal transmitting system including a spurious radiation preventing circuit which comprises a differentiating circuit coupled to a signal line connected to a signal source for differentiating an original signal for emphasizing high frequency components of the signal, an adder circuit for adding the output from the differentiating circuit and the original signal, and a current booster for boosting the output from the adder circuit. The output from the current booster is applied to an output device through a high cut filter, so that spurious radiation from the signal line connecting the signal source with the output device is reduced.
