What is high level AM modulation?
High level AM modulation is a type of modulation using class c (90 percent) amplifiers. The system uses medium power tubes or transistors and is bulky.
What do you understand by modulation?
Modulation is a word applied to anything that varies in level. Brake pads are modulated in an anti lock braking system. The human voice can be modulated whilst singing to give a pleasing sound An audio signal can be superimposed upon a carrier wave in broadcasting. The carrier wave is amplitude modulated by the audio signal.
Why do you need to do modulation?
In a radio system ... Modulation is applied to a carrier. If the carrier wasn't modulated it wouldn't carry any information other than that the transmitter was working. Not very useful. It is the modulation which contains the "information" which we want to send.

Why values of modulation index greater than one are not used in full-carrier AM system?
If the modulation index is greater than 1 (more than 100% modulation) the modulated carrier signal is periodically reduced to zero. This does not effect the transmitter but at the receiver these "dead carrier" intervals result in dropouts in the audio stream from the loudspeaker producing a distorted output that is difficult to understand.
When modulation frequency is doubled the modulation index is halved and the modulating voltage remains constant the modulation system is?
the modulation system is of FM
What do you think is a carrier's maximum modulation index without over-modulation?
The maximum modulation index for a carrier signal without resulting in over-modulation typically depends on the modulation scheme being used. For standard amplitude modulation (AM), the maximum modulation index is generally 1, meaning the peak envelope power of the modulated signal should not exceed the carrier power. In frequency modulation (FM), the modulation index can be higher, but it should still be kept within limits defined by the system to avoid distortion. Ultimately, the precise value can vary based on specific application requirements and the desired quality of the transmitted signal.
When modulation frequency is double the modulation index is halF and the modulating voltage remains constant the modulation system is?
frequency modulation..
How do waves carry signals?
Waves can be varied (modulated) by either changing amplitude (amplitude modulation AM) or changing frequency (wavelength) (frequency modulation FM). The modulations are used to carry the information signal.
What would one use a Class D amplifier for?
A Class D amplifier is a switching or pulse-width modulation amplifier. Class D amplifiers can have either digital or analog inputs and are used for home theater system and mobile phones.
What modulation is used in telegraphy system?
pulse code modulation method used a telephony.
Which cellular system uses the most bandwidth efficient modulation?
I think it is Frequency Modulation with Phase modulation which it the most bandwidth efficient
