Define modulation index. Why is it generally kept less than one ?

1.	Define modulation index. Why is it generally kept less than one ?
Answer» Modulation index is the ratio of amplitude of modulating signal to amplitude of carrier waves. `mu=(A_(m))/(A_(c ))` It is kept low to decrease or noise. A band pass filter rejects low and high frequencies and allows a band of frequencies to pass.
