In a wind-turbine, the generator in the nacelle is rated at 690 V and 2.3 MW. It operates at a power factor of 0.85 (lagging) at its rated conditions. Calculate the per-phase current that has to be carried by the cables to the power electronics converter and the step-up transformer located at the base of the tower.
Consider a satellite communication link with a one way propagation delay of 300ms between the sender and receiver, operating at 10Mbps using packets of length 1500bytes. Length of the ACK packet is also 1500 bytes.
input voltage to an amplifier is: Vi(t)=0.1*cons(2000*pi*t+30) and the output voltage is: Vo(t)=10*sin(2000*pi*t+15) Find the complex voltage gain of the amplifier at f = 1kHz and express the magnitude of the gain in decibels.
Problems for the basic concepts of Induction motor(IM) taking care of slip and syncronous speed and motor speed and its relationship, A 50 Hz induction motor operates in such a way that the slip is 1.45.
A positive charge of 625 nC is uniformly distributed around a circular ring of radius 3 m that is positioned in the x-y plane. The center of the circle is at the origin. The relative permittivity of the medium is Epsilon_r = 1.
1. A transfer function of a low pass filter may be divided into which three response ranges Actual response, ideal response, and straight-line response Gain, ripple, and roll-off Pass band, roll-off, and stop band Attenuation, gain, and roll-off
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.
What happens to the propagation delay of the N-bit full adder as N is increases from 2 bits to 32 bits Compare and contrast this method of building an adder with the carry look ahead method described in your textbook
Write a MATLAB program to compute the capacity of an AWGNC with a given bandwidth and for equally spaced values of between and including and (in dB).
A calibrated RTD with alpha = 0. 0041 / degree C, R = 306. 5 ohm at 20 degree C, and PD = 30 mW / degree C will be used to measure a critical reaction temperature. Temperature must be measured between 50 degree and 100 degree C.
What is correct symbol rate (pulse rate) for this link? What is the bit rate with BPSK modulation? What is the bit rate with QPSK modulation?
a. Given the random binary data sequence 0110001011, provide waveform sketches for (i) NRZ change and (ii)split phase. b.Demonstrate satisfactorily that the split phase waveform can be obtained from the NRZ waveform.
