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

Step-by-Step Verified Solution

Signal bandwidth = 2 fm = 12 kHz

∴\therefore N = 6MHZ12kHZ=6×10612×103=500{{6MHZ} \over {12kHZ}} = {{6 \times {{10}^6}} \over {12 \times {{10}^3}}} = 500
