The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
Modulation schemes depends on frequency.
In Frequency Modulation (FM), if the modulation frequency is doubled, the modulation index does not necessarily double; it depends on the amplitude of the modulating signal. In Amplitude Modulation (AM), the modulation index is defined as the ratio of the peak amplitude of the modulating signal to the carrier amplitude, so it remains unchanged with varying modulation frequency. For Phase Modulation (PM), similar to FM, the modulation index is influenced by the amplitude of the modulating signal and does not inherently double with the modulation frequency. Thus, modulation frequency and modulation index are not directly linked in this way for FM, PM, or AM.
Amplitude modulation (AM) is commonly used in analog amplifiers, especially in radio broadcasting. However, in modern communication systems, techniques like frequency modulation (FM) and phase modulation (PM) are also employed, particularly in digital amplifiers. The choice of modulation depends on the application, desired signal quality, and noise resilience.

It depends on how thick the wall is.
That depends entirely on the species.
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.
