¡ you need to connect a three phase alternator B (incoming generator) in parallel with alternator A which is connected to an infinite bus bar, what are the necessary conditions to make this connection appen properly? Explain how you can use a three lamps to achieve this connection?

Q2

explain the operation of matched filter receiver I we discussed in class, and from your background in Signal and Systems, 16. (10pts) A M-ary QAM system transmits 4.8Kbps with an error rate of less than 10^-6. The center frequency is 1 GHZ and the channel has a bandwidth of 4 KHz. The channel attenuates the signal by 10 dB. The noise in the channel can be modeled as AWGN with a power spectral density of 10^-7 (watts/Hz). Estimate the required transmit signal power, Pt cts) The modulation format is DAM

MacBook Air e 15. From w 12. A communication system uses QAM modulation. The Eb/No is fixed at 15 dB. The application requires a BER of less than 10^-4. What is the maximum number of symbols that could be used? F12 } 1 13: Estimate the bandwidth of a Double Sideband Plus Carrier modulated signal with an amplitude sensitivity (k) of 0.75 and a message bandwidth of 15KHz.

Short answers, 3pts each 11: Estimate the bandwidth of an FM modulated wave given: deviation ratio of 5 and the maximum frequency of the message is 15KHz.

MacBook Air J GE F11 + "/ F12 (25) Determine how 20. (45pts) A battery operated sensor transmits to a receiver that is plugged in to a power outlet. The device is continuously operated. The battery is a commercially available 9 V battery with a 1.1 AmpHr capacity. The application requires a bit rate of 120 Mbps and an error rate of less than 10^-5. The channel has a center frequency of 5.8 GHz, a bandwidth of 20 MHz and a noise power spectral density of 10^-12 W/Hz. The maximum distance is 50 meters and the losses in the channel attenuates the signal by 0.05 dB/meter. M-ary FSK is not possible due to bandwidth limitations. a) (5pts) To maximize battery life, what modulation scheme would you use?
