- The communication system in your college is using a phase modulation of 8 PSK having symbol rate of 500 symbols/s. Your task is to calculate the bit rate for the communication system of your college mentioned above.A line has a signal-to-noise ratio of 1000 and a bandwidth of 4000 kHz. What is the maximum data rate supported by this line? If the bandwidth of the channel is 5 kbps, how long does it take to send a frame of 100,000 bits out of this device? What is the maximum data rate of a channel with a bandwidth of 200 kHz if we use four levels of digital signaling?We use modulation in communication system for many reason, one of the reason for using it in AM is: A. The message signal can transmitted faster with modulation compared to the same signal without modulation. B. To attach interference to the modulated signal in order to transmit it through the medium C. The modulator enhance the noise in the modulated signal using a band pass filter D. The modulator allows controlling the phase of the carrier signal, thus controlling the carrier phase. E. To control the demodulator on the receiver and extract a message signal F. To obtain a active transmitting and receiving of the modulated signal through the antenna

The bitrates need to be added to the transcoder. Calculate the needed bitrates for receiving (Rx) and transmitting (Tx) considering a pooling rate of 4Hz. Tx: 289652580 Rx: 6488574452One way to electrically or optically represent a binary 1 or 0 is to use current state modulation, which represents a binary 1 with the presence of voltage (on a copper cable) or the presence of light (on a fiber-optic cable). Similarly, the absence of light or voltage represents a binary 0.
