Essay

List and describe the three different types of binary signaling techniques.
In return-to-zero, the absence of a voltage, or zero volts, represents a 0 bit and an increase in voltage represents a 1 bit. The signal rises and falls within a bit time period. In non-return-to-zero, the voltage does not change when the next bit is the same as the previous bit. Non-return to zero level, works the same way as non-return- to-zero, but the voltage changes between a positive and negative level, rather than between a positive voltage and zero volts, as in the previous two techniques.
