Amplitude modulation is one way to carry information on a carrier, such as a
radio signal. Another way is FM (Frequency Modulation). While FM offers greater
clarity for audio, and the higher frequencies that FM use offer a wider
bandwidth, allowing for more information to be transmitted, one application
where FM and digital are not suitable are Aviation communication, which to this
day still use AM analogue. This is because weaker signals can be heard over
stronger, closer ones with AM, allowing for emergency transmissions to have
more chance of being heard over other traffic. Also, AM uses a narrower
bandwidth than FM, allowing more users in a smaller space. This is important for
the lower frequencies of Radio, where space is at a premium (ie shortwave
bands).

What is the modulation index called when it is expressed as a percentage?
When the modulation index is expressed as a percentage, it is commonly referred to as the "percentage modulation." This representation indicates the extent of modulation in relation to the carrier signal, showing how much the amplitude of the carrier varies due to the modulating signal. It provides a clearer understanding of modulation depth for practical applications in communication systems.

What are benefits of analog modulation technique?
Analog modulation techniques offer several benefits, including simplicity in implementation and ease of understanding, making them suitable for various applications. They typically require less complex equipment than digital modulation, which can result in lower costs for transmission systems. Additionally, analog modulation can provide better performance in terms of signal quality over short distances and is effective for continuous signals, such as audio. However, it is generally more susceptible to noise and interference compared to digital modulation.
Amplitude modulation applications?
In olden days all radio stations followed only amplitude modulation to propagate the signals. Presently still some of the radio stations follow the same and mostly have switched over to frequency modulation. Especailly in tv transmission the picture signal is propagated only by amplitude modulation.
What is percentage power saving if AM transmitter with modulation index m equals 0.5 is replaced by SSBSC transmitter with same modulation index?
The percentage power saving when replacing an AM transmitter with modulation index of 0.5 with an SSBSC transmitter with the same modulation index would be approximately 93.75%. This is because SSBSC transmitters only transmit one sideband, while AM transmitters transmit both sidebands, resulting in less power usage and more efficiency.
