Question

A bandwidth of $6\text{MHz}$ is available for A.M. transmission. If the maximum audio signal frequency used for modulating the carrier wave is not to exceed $6\text{KHz}$ . The number of stations that can be broadcasted within this band simuntaneosuly without interfering with each other will be

• A. 500
• B. 500.0
• C. 500.00

Answer 1

Answer: (A), (B), (C)

Bandwidth for each station $=2\times$ maximum frequency of audio signal$=12\text{KHz}$

Given that available bandwidth is $6\text{MHz}$

The number of stations that can be broadcasted within this band simuntaneosuly without interfering with each other will be $\frac{6\times {10}^6}{12\times {10}^3}=500$

Ans: $500,500.0,500.00$
