**Question No.1**

**a)**

**Calculate the bandwidth required of the given AM Station with proper unit.**

**Modulating signal with bandwidth of 7 KHz.**

**Solution: -**

_{t }= 2 * BW

_{m , }where BW

_{t }= Total Bandwidth and BW

_{m }= Bandwidth of modulating signal

_{t }= 2 * 7 = 14

**b)**

**Calculate the bandwidth required of the given FM Station with proper unit.**

**Modulating signal with frequencies of 10000 to 19000 Hz.**

**Question No. 2**

**Suppose, if the bandwidth of the medium is 16,000Hz and the difference between the two carrier frequencies (fc1 and fc0) is 2000Hz, and the transmission is in full duplex mode. Find the maximum baud rate for FSK signal in each direction with all necessary calculation and proper unit.**

_{1 }– fc

_{0}) + NBaud

_{1 }and fc

_{0 }are the carrier frequencies then:

_{1 }– fc

_{0})

**Transmission is full duplex mode: -**

**Max Baud Rate = Bandwidth/2 -**

**(**fc

_{1 }– fc

_{0})
