Question

An audio signal consists of two distinct sounds, 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 bandwidth required to send both the signals together to the $AM$ signal bandwidth requried to send just the human speech is $\frac{6}{x}$. Find x the value of $x$.

Answer 1

Answer: 1

Ratio of $AM$ signal Bandwidths
$=\frac{15200-200}{2700-200}=\frac{15000}{2500}=6$
