What is the main disadvantage of FM over AM?
What is the main disadvantage of FM over AM.
Explanation: The disadvantage of FM over AM is that in frequency modulation large bandwidth is required.
While, in case of advantages, FM is less prone to noise interference and has lower power consumption compared to AM..
What is the point of AM radio?
An AM receiver detects amplitude variations in the radio waves at a particular frequency, then amplifies changes in the signal voltage to operate a loudspeaker or earphone.
What is the disadvantage of FM?
Disadvantages of FM: Much more Bandwidth (as much as 20 times as much). More complicated receiver and transmitter.
What are the applications of AM?
Amplitude modulation applications Broadcast transmissions: AM is still widely used for broadcasting on the long, medium and short wave bands. … Air band radio: VHF transmissions for many airborne applications still use AM. .
What are the advantages and disadvantages of AM and FM?
Advantages of FM over AM All the transmitted power in FM is useful, while in AM most of the transmitted power is in carrier which contains no information. The amplitude of FM is constant which makes it independent of the modulation deption, while in AM modulation depth directs the transmitted power.
