What is the need for modulation?
Answer Posted / aaron sharaon
modulation-it is the process of varing a periodic waveform.
for eg:a tone in order to use that signal to carry a
message. periodic waveform is a sine wave which repeats
itself. normally a high frequency sino sidal waveform is
used as a carrier signal. the three key parameters of a
sine wave are amplitude,frequency,n phase all of which can
be modified in accordance with the low frequency
information signal to ontain a modulated signal.
well uhh....i dont know what is it's need plz check 4m d
above.
