AM AND FM
AM means "amplitude modulation". The amplitude of
the radio wave oscillates over time. The frequency of
the radio wave is constant. The peaks of the wave get
taller and shorter. The rate at which the amplitude
fluctuates corresponds to the pitch. How much it
fluctuates corresponds to the volume.
FM means "frequency modulation". The amplitude of
the radio wave is constant. The frequency varies a small
amount. The peaks of the wave get closer together and
further apart. The rate at which the frequency varies
corresponds to the pitch. How much it varies
corresponds to the volume.
Radio broadcasting uses either
of two types of signals - AM or FM.
FM broadcasting is a broadcast
technology invented by Edwin Howard Armstrong
that uses frequency modulation (FM) to provide high-
fidelity sound over broadcast radio.
FM signals do not need expensive transmission
FM Radio enables a great degree of localization and
hence brings along interactivity with a local flavour,
at relatively low broadcast costs, which cannot be
matched by television.
Programming Policies: From the late '70s, the radio
channel has been plagued by archaic programming
policies, incongruous censorship norms, and it
sidelined its brightest stars in all departments.
Obsolete technology: its outdated medium wave
technology and poor sound, it will not be able to lure
away listeners from FM.
Bureaucratic Work Culture: Bureaucratic control,
tight-fisted attitudes, constant shuttling of staff between
AIR and DD; misjudgments.
AIR informs, educates and entertains
All India Radio keeps the people all over the country
informed quickly about Government policies, plans,
programs and achievements.
In this era of Notebook, Smartphone, importance of
Radio remained same as like before.
