Explanation:
AM
- AM stands for Amplitude Modulation.
- It is a method of transmitting signals by changing the amplitude of a carrier wave in relation to the waveform being sent.
- This modulation technique is widely used in radio broadcasting.
- In AM, the strength or amplitude of the carrier signal is varied in proportion to that of the message signal.
- The modulated signal is then transmitted through the air and received by a radio receiver, which extracts the original message signal.
Advantages of AM:
- Simple and economical to implement.
- Can cover long distances with less power compared to FM (Frequency Modulation).
- AM receivers are less complex and cheaper than FM receivers.
- AM signals can propagate over mountains and hills better than FM signals.
Disadvantages of AM:
- More susceptible to noise and interference compared to FM.
- Limited in audio fidelity due to its narrower bandwidth.
- Cannot carry as much information as FM signals.
Conclusion:
- While AM has its limitations, it continues to be a popular choice for broadcasting, especially in the case of talk radio and news stations. Its simplicity and ability to cover long distances make it a reliable option for many radio stations.
