During a short-circuit test on a single-phase 2300/208-V 500-kVA 60-Hz distribution transformer, the following test values were obtained:VSC = 95V; ISC = 218A; PSC = 8.2kWCalculate the parameters RE and XE, and the maximum efficiency and power output for the transformer when a load with a 90% lagging power factor is connected to the transformer secondary winding.
Consider an 8-user CDMA system. The data vector of all users is given by [1,1,1,1,-1,-1,-1,1]. Find the total transmit signal.
Discuss the trade-offs between fiber optic and satellite communication in terms of costs, signal capacity, signaling method, interference, likelihood of failure and repair issues, multipoint capability, reconfiguration capability, and noise.
a) Based on your decision create a sampled signal of the sum of the two sines, and plot the magnitude of the zero centered FFT with property frequency annotation. Did it work Check with the data tip tool.
A barometric pressure transducer is measuring pressure between 800 and 1100 mbars. If the transducer output is scaled to 0-5V and input to the HCS12 ATD confugured in 8-bit mode, what is the pressure measured when the ATD output = 0x5A
A transformer is used to match an 8 ohm speaker to a 500ohm audio line. What is the turns ratio of the transformer what is the input voltage and output voltage when 15W is being delivered to the speaker
