why is an FM signal less susceptible to noise than AM signal ?
What is amplitude modulation?
an audio signal is not transmitted directly by converting it into an electromagnetic wave of same frequency.give 2 reasons.
KINDLY PROVIDE THE SOLUTION OF PHYSICS CLASS 12 SET 55/3 OF BOARD 2013 SOON?
pls explain modulation and demodulation???/
draw a plot of variation of ' amplitude ' versus 'w ' for an amplitude modulated wave. hence explain the need for keeping the broadcast frequencies sufficiently spaced out ?
The block diagram of AM transmitter and AM receiver
what is html?explain in detail?
what does line of sight communication means???
Why do long distance radio broadcasts use shortwave bands?
A message signal of frequency 10kHz and peak voltage 10 V is used to modulate a carrier of frequency 1 MHz and peak voltage of 20V.Determine
a) Modulation Index
b) the side bands produced

Two identical bodies are made of a material for which the heat capacity increase with temperature. One of these is at 100o C, while the other one is 0o C. If the two bodies are b ought into contact then, assuming no heat loss, the final common temperature is :
(1) less than 50oC but greater than 0o C (2) 0o C
(3) 50o C (4) more than 50o C
