a boost converter operates at 20 khz, and converts power from a solar panel to a battery bus. the panel has norminal volate of 16v and current up to 3 A. the battery bus is 48 v. the transistor can be modelled as a 0.5 v constant forward drop. while diode is a 1.0 v drop, which device dissipates more power? what is the converter efficiency?
Is the high carrier concentration in transparent conductors due to their ideal band structure or to the presence of defects and dopants. If two different materials but with the same work function are brought into contact, does band bending result.
To the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 26.0m/s .If nothing is done to correct its orbit
A balanced Y-connected power system is known to have Van=100
Construct the RC differentiator. Set the channel 1 input coupling switch to dc. Next adjust the dc offset, amplitude, and frequency controls of the function generator to produce the input waveform.
the hd cable signal send out is usually ranging between (1-25mv), with the frequency range from 1000Hz- 20Khz. An amplifier will gain 46 db will boost the signal before sending it through the cable connection.
Assume the motor is connected in wyne and that each branch can be represented by a resistance R in series with an inductive reactance X. (a) Calculate the value of R and X. (b) What is the phase angle between the line current
Suppose we transmitted 5 cos wct for logic one and 15 cos wct for logic zero. Find the maximum signal energy. Design a demodulator and show the detection criterion for the output of the demodulator. Finally, find the bit error-rate.
What effect do internal capacitances in the transistor model have on practical performance of a real system? How would you use these model values to predict system performance?
If we have a 600ohm transmission line terminated with a 1200ohm resistor, how long must the transmission line be if the input impedance is purely real?
Maximum Likelihood to get the above parameters i.e. u0 and var. Now from these 999 points, I take one point out (lets call it i) and add a new point (lets call it j). What will the new mean and variance be?
Design a circuit to multiply a 2-bit unsigned magnitude binary number by 1, 2, 3, or 4 to produce a 4-bit output
