If an amplitude modulation (AM) has an amplitude modulating signal of 0.5 V and carrier amplitude of 1.3 V, what is the modulati
1 answer:
Answer:
The modulation index in the amplitude modulation will be 0.384
Explanation:
We have given amplitude of adulating signal
Amplitude of carrier signal
We have to find modulation index
Modulation index is the ratio of amplitude of modulating signal and amplitude of carrier signal
So modulation index
So the modulation index in the amplitude modulation will be 0.384

Answer:
The amplitude of vibration of string will increase due to which loudness of sound will increase
Explanation:
As we know that the guitar is based on the principle of Resonance. When string of the guitar vibrates at a given frequency then the sound produced in the hollow part of the guitar will also be at same frequency.
This is known as resonance condition, so guitar will produce same frequency sound as that of frequency of string.
Now if the string is plucked with increasing level of force then it will increase the amplitude of vibrations of the string due to which the sound produced in the guitar will also be of same level.
So here we can say that amplitude and intensity of sound related as
so on increasing amplitude the intensity will increase and hence it will produce loud sound
