Q. While there is (are) only _____ way(s) to send parallel data, there is (are) three subclass(es) of serial transmission.

View solution

Q. In ______ transmission, we send 1 start bit (0) at the beginning and 1 or more stop bits (1s) at the end of each byte.

View solution

Q. In _________ transmission, we send bits one after another without start or stop bits or gaps. It is the responsibility of the receiver to group the bits.

View solution

Q. The ________ mode provides synchronization for the entire stream of bits must. In other words, it guarantees that the data arrive at a fixed rate.

View solution

Q. A _________ digital signal includes timing information in the data being transmitted.

View solution

Q. In decoding a digital signal, the receiver calculates a running average of the received signal power, called the _______.

View solution

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

View solution

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

View solution

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

View solution

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

View solution

Q. 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.

View solution

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

View solution

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

View solution

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

View solution

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

View solution

Q. 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.

View solution

Q. In ___________ there is always a transition at the middle of the bit, but the bit values are determined at the beginning of the bit. If the next bit is 0, there is a transition; if the next bit is 1, there is none.

View solution

Q. In Manchester and differential Manchester encoding, the transition at the middle of the bit is used for __________.

View solution

Q. The minimum bandwidth of Manchester and differential Manchester is ____ that of NRZ.

View solution

Q. In _______encoding, we use three levels: positive, zero, and negative.
