bipolar definition
Can anyone tell me a full definition of unipolar and bipolar voltages please?
If these terms are used for energy power, then it must be replaced by the terms of DC and AC, respectively. The terms are used for the electrical signals to the analog information or transmitting a digital device to another. Transmitter to the receiver: a) Analog: Unipolar: Tension can be only one polarity. Only the magnitude of changes voltage depending on the value of the signal. Bipolar voltage can be positive and negative polarity, together with the evolution of the magnitudes to represent the sign and magnitude of value represented by the electrical signal. b) Digital: Unipolar: Standard data represents the logical sequence and zero positive voltage above a threshold and low (near zero) voltage below a threshold. Bipolar: Serial data stream representing logical ones and zeros, either by time-phase changes from positive to negative and vice versa, or the duration of the pulses, or by the polarity of the pulses. There may be two or three states involved in a bipolar order flow data: return to zero NRZ = = not only been positive and negative RZ = = revert to zero in three states: positive (= 1) negative (= 0) at rest (= low level near zero volts, used for self-clocking the serial data stream)
