Scenario description: assume you got a new wireless sensor device with circuit power consumption of p_elec = 0.015mw. frequency bandwidth (i. e. symbol rate) is 1mhz. you have a packet with 125 bytes to send. assume there is no other overhead, and you can ideally turn on and off the transmission without additional power cost. now you can choose using various data rates to transmit this packet, while maintaining the same ber at 0.0001 with the following assumption: using bpsk, the required tx amplifier power consumption of p_t =0.02mw; using qpsk, the required tx amplifier power consumption of p_t =0.05mw. receiver energy consumption is not a concern. questions: calculate the energy consumption (in unit of nj – nano-joule) of transmitting this packet, using bpsk and qpsk schemes, respectively. do you prefer slow bpsk transmission to save power, or to transmit quickly with qpsk and then sleep?

Write a computer program to calculate the three-phase fault current for a fault at f in figure 1.16, with the network normal, and with one line at a time removedproblems 1.1 write a computer program to calculate the three-phase fault current for a fault at f in figure 1.16, with the network normal, and with one line at a time removed 20 power system relaying from service. the positive-sequence impedance data are given in the accompanying table. use the commonly made assumption that all prefault resistance values are (1.0+j0.0) pu, and neglect all resistance values. calculate the contribution to the fault flowing through the cb b and the voltage at that bus. for each calculated case, consider the two possibilities: cb b2 closed or open. the latter is known as the stub-end fault í• figure 1.16 problem 1.1 system data for figure 1.16 from to positive sequence 0.0+j0.1 0.05j0.15 0.04 j0.2 0.01 jo.i 0.015 + j0.15 0.01 j0.19 0.01 +j0.19 0.03+j0.1 0.0+j0.08 6 6 6 from service. the positive-sequence impedance data are given in the accompanying table. use the commonly made assumption that all prefault resistance values are (1.0 + j 0.0) pu, and neglect all resistance values. calculate the contribution to the fault flowing through the cb b1, and the voltage at that bus. for each calculated case, consider the two possibilities: cb b2 closed or open. the latter is known as the “stub-end” fault.
