Digital Signal Transmission - an overview ScienceDirect Topics

WebMany different mediums can be used to transmit digital signals electrically. Electrical cable, in the form of a twisted pair or coaxial cable, is commonly used as the transmission path. However, in some industrial environments, the noise levels are so high that even digital data becomes corrupted when transmitted as electrical pulses. Web16 dec. 2008 · Noise could be transient (temporary) or constant. Unpredictable transient noise is caused, for example, by lightning. Constant noise can be due to the predictable 50 or 60 Hz AC ‘hum’ from power circuits or harmonic multiples of power frequency close to the data communications cable. dr jane glassco
