The ........... rate defines the number of data elements sent in 1s; the ............ rate is the number of signal elements sent in 1s.

The signal rate is sometimes called the .......... rate.

The data rate is sometimes called the .......... rate.

In a .......... scheme, all the signal levels are on one side of the time axis, either above or below.

In ............... schemes, the voltages are on the both sides of the time axis. For example, the voltage level for 0 can be positive and the voltage level for 1 can be negative.

In ............, the level of the voltage determines the value of the bit

In ............, the change or lack of change in the level of the voltage determines the value of the bit.

The idea of RZ and the idea of NRZ-L are combined into the ............. scheme

The idea of RZ and the idea of NRZ-I are combined into the .............. scheme.

In .............. encoding, the duration of the bit is divided into two halves. The voltage remains at one level during the first half and moves to the other level in the second half. The transition at the middle of the bit provides synchronization.
