I. Reading Exercises:

Exercise 1. Read and memorize using a dictionary:

newscasts, local programming, remote broadcasts, satellite TV, Doppler weather radar, forecasts, simulcast, station identification, barter, summit, embedded, over-the-air, effective radiated power, backup generator, electromagnetic interference, analog shutdown

Exercise 2. Answer the questions:

  1. What are television studio usually used for?

  2. What is another significant part of a station?

  3. Where is radio antenna often located on?

  4. What advantages do VHF stations possess?

Exercise 3. Match the left part with the right:

1. In North America, full-power stations on band I are

1. ,and have no production facilities of their own.

2. There is also a section where electronic news gathering operations are

2. no stations on channel 37 in North America for radioastronomy purposes.

3. Since at least 1974, there are

3. generally limited to 100 kW analog video.

4. Some stations only simulcast another, usually the programmes seen on its owner's flagship station

4. based, receiving remote broadcasts via remote pickup unit or satellite TV.

Exercise 4. Open brackets choosing the right words:

Weather (was/is) also (the/a) significant part (for/of) the station. Stations (without/with) newscasts also (has/have) their own meteorologists and Doppler weather radar, and (produced/produce) their own forecasts, (when/which) often vary from station to station. In (-/the) U.S., most NBC stations now (are carring/carry) Weather Plus on a second digital channel, which (mixed/mixes) national and local segments.

The Speaking Module

II. Speaking Exercises:

Exercise 1. Describe these words: (analogue signal, doppler weather radar, station identifications,) using the suggested words and expressions as in example:

analogue signal

is varied; with respect to; transmission; degraded by noise

example:

In an analogue signal, the signal is varied continuously with respect to the information. During transmission the information contained in analogue signals will be degraded by noise.

doppler weather radar

weather, significant, meteorologists, forecasts, to vary; in the U.S., digital channel, national segments

station identifications

not simulcast, to produce, TV graphics; sister stations; barter, some cases

summit

radio antenna , top of a, skyscraper, transmitter link, signal; telemetry, sub carriers, main broadcast; to retransmit , to pick-up, over-the-air

backup generators

VHF stations, antenna, long wavelength, radiated power, electricity bill; full-power stations, analog video; long-distance reception

Exercise 2. Ask questions to the given answers:

1) Question: ___________________________________________ ?

Answer: There is usually a news department, where journalists gather information.

2) Question: ___________________________________________ ?

Answer: Stations with newscasts also have their own meteorologists and Doppler weather radar.

3) Question: ___________________________________________ ?

Answer: Most stations which are not simulcast produce their own station identifications.

4) Question: ___________________________________________ ?

Answer: Stations which retransmit or simulcast another channel may simply pick-up the station, over-the-air.

5) Question: ___________________________________________ ?

Answer: Since at least 1974, there are no stations on channel 37 in North America for radio astronomy purposes.
