Modulation is the method by which a high-frequency digital
signal is grafted onto a lower-frequency analog wave, so
that digital packets are able to ride piggyback on the
analog airwave.

Answer / rohan apte

The easier answer to this is that... Modulation is the
process of varying one or more properties of high frequency
periodic waveform, called the carrier signal, with respect
to a modulating signal. This is done in a similar fashion
as a musician may modulate a tone (a periodic waveform)
from a musical instrument by varying its volume, timing and
pitch. The three key parameters of a periodic waveform are
its amplitude ("volume"), its phase ("timing") and its
frequency ("pitch"), all of which can be modified in
accordance with a low frequency signal to obtain the
modulated signal. Typically a high-frequency sinusoid
waveform is used as carrier signal, but a square wave pulse
train may also occuris a method by which a high frequency
digital signal is converted to a low frequency anlaog signal
