A 160-ft-diameter parabolic antenna is driven by a 10-W transmitter at 4.3 GHz. Calculate its effective radiated power (ERP) and its beamwidth.
An electron is traveling horizontally along the positive x-axis at a speed 3.00 x 106 m/s. After it passes the origin, it enters a constant E field with a strength of 200 N/C and directed 45 degrees up from the x-axis.
A 3-phase, 11 kV, round-rotor synchronous generator delivers power to an infinite bus whose line-to-line voltage is constant at 11 kV rms. The effective stator resistance and synchronous reactance per phase of the synchronous generator are respectiv..
A 37.5-kVA, 6900-230V, 60Hz, single phase transformer is operating in the step down mode at rated load, rated voltage, and 0.68 power factor lagging. The equivalent resistance and reactance referred to the low side are 0.0224Ω and 0.0876Ω
(a) Design a high-pass filter with a cutoff frequency of 40 kHz. Use 0.01 uF capacitor and an appropriate resistor. B) Sketch and label the circuit. C) What is the gain of the filter at the cutoff frequency Give your answer both as ratio (Vout/Vin..
The receiver takes the three received bits and decides which bit was sent by taking the majority vote of the three bits. Find the probability that the receiver makes a decoding error.
A particular communications system has 2 identical receiver stages connected in cascade, each with gain 7 dB and noise figure 4 dB. Compute the noise figure of the combination assuming the stages are impedance matched.
When the scope probe is properly calibrated, it can be modeled as a 9[M Ohm] resistor in parallel with a capacitor having a capacitance l/9th that of the oscilloscope input capacitance.
In transformer designs, often you can find an air gap in the core. In all the electric machines, there is an air gap between the stator and rotor. In both cases, flux will go through both core material and the air gap.
The following calculation was performed by a particular breed of exceptionally intelligent cartoon character. If the radix r used by the character corresponds to its total number of toes, how many toes does the character have on each foot
A certain sawtooth generator has the following parameter values: Vin: 3v, R: 4.7kohm, C:0.001uf. Determine its peak-to-peak output voltage if the period is 10 us. What is the Vpp
A 115/28 V transformer has 56 turns on its low voltage side. How many turns does it have on its high voltage side what is its turns ratio when it is used as a step-down transformer
it is required to establisg a chart for count of nonconformities for a manufacturing process. if 25 units are to be inspected and the total number of the count of nonconformities from all the units is 141, determine the central line and control li..
