An audio signal consists of two distinct sound. One a human speech signal in the frequency band of `200Hz` to `2700Hz`, while the other is a high frequency music signal in the frequency band of `10200Hz` to `15200Hz`. The ratio of the AM signal together to the AM signal band width required to send just the human speech is:
