A bandwidth of 6MHz6MHz is available for A.M.A . M . transmission. If the maximum audio signal frequency used for modulating the carrier wave is not to exceed 6kHz.6kHz . The number of stations that can be broadcasted within this band simultaneously without interfering with each other will be __________.

Correct answer

0

Step-by-step solution

Band width =2×n×= 2 \times n \times highest modulating frequency.
6MHz=2×n×6KHz6MHz = 2 \times n \times 6KHz
⇒n=6×1062×6×103=500⇒ n = \dfrac{6 \times {10}^{6}}{2 \times 6 \times {10}^{3}} = 500
