Balanced signals will generate EMI with opposing polarity, such that the EMI is largely canceled out. Twister pair is also useful when it is important to minimize the generation of EMI. This is why twisted pair is the proper cabling for differential signals: the close physical proximity of the two wires ensures that EMI will be coupled almost equally into both conductors, which in turn ensures that the differential receiver circuitry will eliminate this noise. This makes differential systems more robust against noise-as long as the noise is present in both signals. A differential receiver subtracts the negative signal from the positive one, meaning that any voltage components present in both signals will be eliminated. A differential system can also be referred to as a balanced system, because the two signals are "balanced" on either side of the common-mode voltage. Twisted-pair cable is especially valuable when used with two signals that transmit information differentially, i.e., using positive and negative versions of the same signal. This tool will also provide the signal propagation delay, capacitance, and inductance per unit length. This calculator computes the characteristic impedance of a twisted-pair cable based on its dimensions. It is important to determine the characteristic impedance of a twisted-pair cable because this impedance should match the impedance of the transmitting and receiving circuitry. Twisted pairs are used with balanced signals. A twisted-pair cable is simply two wires that are twisted together so as to reduce radiated EMI (electromagnetic interference) and mitigate the effects of received EMI.
