Using MATLAB, plot the pole zero map and the Bode plot of the two transfer functions and paste the graphs below. Identify and briefly discuss the differences between the Bode plot of the two transfer functions.
A three-phase, 2000-kVA, 12-kV, 1800-rpm synchronous generator has a synchronous reactance of 20 ohms per phase and negligible armature resistance.a. The field current is adjusted to obtain the rated terminal voltage at open circuit.
Four voice signals. each limited to 4 kHz and sampled at Nyquist rate are converted into binary PCM signal using 256 quantization levels. what will be The bit transmission rate for the time-division multiplexed signal.
A 15 hp, 209V,three-phase,six pole, Y-connected induction motor has the following parameter values per phase: R1= 0.128 ohm, R'2=0.0935 ohm Xeq- X1 + X'2 = 0.49 ohm. The motor slip at full load is 3%, and the efficiency id 90%.
calculate the average signal-to-noise (SNR) in decibels (dB) Assume equal numbers of binary 0s and 1s.
define hue (h) in the h-i-s coordinate system. outline how the formula for computation of hue from R-G-B coordinates of a color point may be derived (detailed derivation is not required)
Explain in detail on the fabrication process of the FINFET. You must show a 3-dimensional view of FINFET and label the its L and W, the length and width of the gate.
Measurements show that for a particular arrangement of the equipment and at a particular amplifier setting, the system will howl if 1% of the output power is fed back to the microphone. Estimate the power gain of the P.A. amplifier in decibels.
An ultrasound image analog signal needs to be converted to a digital bit stream. The bandwidth of the signal is from 500 kHz to 2.0MHz, and the necessary resolution is 12 bits. determine the required sampling rate and the data rate
The average voltage across the load when the triggering angle is 140 degrees. Keep in mind that the conduction is incomplete when the triggering angle is greater than 140 degrees.
A Si IMPATT diode is operated at 140 GHz with a dc bias of 15 V and an average biasing current 150 mA. (a) If the power conversion efficiency is 25% and the thermal resistance of the diode is 4OoCnV.
