Exam 4: Manipulating Information for Transmission

The problem associated with using start and stop bits is the amount of ________ used every time a character is sent.

The term toll ________ refers to a voice signal that meets the toll voice specifications provided by standards organizations.

Sampling is the process that formats the PCM words and ships them out onto the physical transmission medium, whether it is a copper wire or a fiber-optic strand.

In analog data transmission, frequencies of 0 to 300 Hz and 3300 to 4000 Hz are reserved as ________, used to ensure that the data transmission will not interfere with other signals.

In ________ transmission, the use of one clock to reference the start and stop of the bit stream allows the equipment to send characters without individual stop and start bits.

The three common digital patterns are ________, bipolar nonreturn to zero (BPNRZ), and bipolar return to zero (BPRZ).

The most popular encoding scheme for personal computing devices is ________.

Which of the following is a major problem associated with the use of FDM?

How many signaling changes/changes in the waveform occur per second in a 2400 baud per second circuit?

In communications, the term ________ refers to information being transmitted using a one state or a zero state.

Which of the following is not one of the stages occurring in the process of analog-to-digital conversion?

The amount of data the analog data circuit is able to carry depends on the:

A two-way radio is a good example of a:

________ signals are difficult to synchronize and hard to monitor with error-checking schemes because there are no opposite polarity pulses to count.

FDM is a viable multiplexing method for certain applications such as DSL, which is used for short distances between central offices and subscribers' locations.

In a digital-to-digital conversion, the interface equipment formats the digital signal into a(n) ________ signal before transmitting it out onto the network.

The individual signal riding within the multiplexed signal is called a(n) ________.

Techniques such as ADPCM and LD-CELP have been created to compress the voice signal and reduce the number of ones and zeros needed for each PCM word.

The acronym for the eight-bit code that IBM developed specifically for their machines, which is seldom deployed today is ________.

Bipolar non-return to zero provides the best method for transmitting digital signals longer distances.
