Analysis of the general digital signals for EMC purpose

Abstract. In the paper discussed and the comparison of two digital signals. The rising and falling edge of the first signal has the same. The spectrum of this signal is well known from the various literatures. The different rising and falling times has the second signal, what represents a general technical digital signal. This paper provides calculation of spectra of such a signal. Presented paper also contains the calculation of the radiation interferences of the current loop fed with the both analysed signals. Based on the obtained results the thesis is formulated, enabling to reduce radiation of the device when it is processing general digital signal.
