Amplitude modulation (AM) is a modulation technique used for transmitting information via a radio carrier wave. In AM, the amplitude of the carrier wave is varied in proportion to the waveform being transmitted, such as sounds or television pixels. AM has a wider coverage area than FM due to atmospheric propagation. It also allows for long distance propagation because of its wavelength. However, AM signals are not as strong as FM when propagating to obstacles, and only one sideband of the AM signal transmits information, losing power in the other sideband and carrier. Additionally, noise mixes with the AM signal through propagation, making it more difficult to recover the original signal at the receiver. AM is used in radio frequency transmissions.

2.  Amplitude modulation (AM) is
a modulation technique used in electronic
communication, most commonly for transmitting
information via a radio carrier wave. In amplitude
modulation, the amplitude (signal strength) of the
carrier wave is varied in proportion to the waveform
being transmitted. That waveform may, for instance,
correspond to the sounds to be reproduced by
a loudspeaker, or the light intensity of television pixels.

8. 1.Corverage area of AM Receiver is wider than FM
because atmospheric propagation.
2 AM is long distance propagation because λ
3 AM Circuit is chapter and non complex than FM.
4. AM have bandwidth limited and FM unlimited

9. 1. Signal of AM is not stronger than FM when it
propagate to obstacle.
2. Only one sideband of AM transmits Information
Signal, So it loss power on other sideband and Carrier.
3. Noise mixes AM Signal in amplitude when it
propagates in free space that it make difficulty to
recover Original Signal at receiver.
