Television
 Television is a telecommunication
medium used for transmitting
sound with moving images in black
and white, or in color, and in two
or three dimensions:
Television
TV set
TV
transmission.
TV
program

3.
Television is mass medium
Entertainment Education
News Advertising

 Television become available in crude experimental forms in the late
1920s. After world war-2, an improved from became popular in the
United State and Britain, and television sets became commonplace in
homes, businesses, and institutions.
 During the 1950s television was the primary medium for influencing
public opinion.
 In the mid -1960s color broadcasting was introduced in the US and
most other developed countries.
 A standard television set is composed of multiple internal electronic
circuits, including a tuner for receiving and decoding broadcast
signals. A visual display device which lacks a tuner is correctly called a
video monitor rather than a television.

5.
Radio
Radio is the use of radio
waves to carry
information, such as
sound, by systematically
modulating some property
of electromagnetic energy
waves transmitted through
space, such as their
amplitude, frequency,
phase, or pulse width.

6.
 When radio waves strike an electrical conductor, the
oscillating fields induce an alternating current in the
conductor. The information in the waves can be extracted
and transformed back into its original form.
 Radio systems need a transmitter to modulate some
property of the energy produced to impress a signal on it,
For example :
Using amplitude modulation or angle modulation.

7.
 Radio systems also need an antenna convert electronic
currents into radio waves, and vice versa. An antenna can
be used for both transmitting and receiving.
 The electronic resonance of tuned circuits in radios allow
individual stations to be selected.
 The electromagnetic wave is intercepted by a tuned
receiving antenna. A radio receiver its input from an
antenna, and converts it into a form usable for the
consumer, such as sound, pictures, digital data,
measurement values, navigational positions, etc.
 Radio frequencies occupy the range from a 3 kHz to 300
GHz, although commercially important uses of radio use
only a small part of this spectrum.

8.
 A radio communication system sends signals
by radio. The radio equipment involved in
communication systems includes a
transmitter and a receiver, each having an
antenna and appropriate terminal
equipment such as a microphone at the
transmitter and a loudspeaker at the
receiver in the case of a voice
communication system.

E-media (ElectonicMedia)
 Electronic media are media that use
electronics or electromechanical energy for
the end user (audience) to access the
content. This is in contrast to
static media (mainly printmedia), which
today are most often created
electronically, but do not require
electronics to be accessed by the end user
in the printed form.”

 Electronic media are media that use electronic or electromechanical
energy for the end user to access the content. This is in static media,
which today are most often created electronically but do not require
electronics to be accessed by the end user in the printed form.
 The primary electronic media sources familiar to the general public are
video recordings, audio recordings, multimedia presentations, slide
presentation, CD-ROM, and Online content.
 Most new media are in the form of digital media. However, electronic
media may be in either analogue electronics data or digital electronic data
format.

11.
 Although the term is usually associated with content
recorded on a storage medium, recordings are not
required for live broadcasting and online networking.
 Any equipment used in the electronic communication
process may also be considered electronic media.
For Example:
Television, radio, telephone, desktop, computer,
game console, handheld device etc.
