Design an analog Chebyshev-II lowpass filter that has a 0.25 dB or better ripple at 250 Hz and at least 40 dB of attenuation at 400 Hz. Plot the magnitude response, the log-magnitude response in dB, the group-delay, and the impulse response of the filter.
In a processing plant, a chemical tower has a liquid which is vaporized. However, if the vapor in the tower reaches 150°C, an alarm needs to be generated so that safe shutdown of that system of the plant may be initiated. An RTD will be used to measu..
A 22KVA, 2300/230 VAC, 60HZ transformer is tested with a short circuit test. The measured data are as follows: Psc=280W, Vsc=80VAC and Isc=9.5 A 1. Find the transformer turns ratio of the transformer
What property of the space charge region contributes to the collection of charge carriers and which is not present in the neutral regions where movement and collection are by diffusion. Which resistance term does this affect, series resistance, RS,..
Suppose the field to be imaged contains 3 parallel bars of width W mm, spread nonuniformly, with the darkness profile. Determine the darkness profile of the bars after imaging. Can you still tell all the bars apart
Simulate the second-order RLC circuit using simpower Matlab simulink.This circuit has DC source voltage Vs=220V, Inductance L=2mH and Resistance R=160 ohms.Determine the capacitance values for each case
Consider a 4-bit counter made with JK flip-flops with preset and clear inputs. Describe the changes/additions that need to make the counter reset after counting to 1001. Be sure to state any assumptions that are made.
Suppose that we are designing a cardiac pacemaker circuit. The circuit is required to deliver pulses of 1-ms duration to the heart, which can be modeled as a 500 ohm resistance. The peak amplitude of the pulses is required to be 5 volts.
Design (determine) the metallurgical channel thickness of an n-channel silicon JFET such that the pinch off voltage is -3.0V. The doping parameters are NA=3x1018cm-3 and Nd=2x101616 cm-3.
a pn-junction is uniformly doped and has dopant concentration of na 4 x1016 cm-3 in the pregion at 300k. at zero bias
A gaseous mixture containing 50 mol% hydrogen and 50 mol% acetaldehyde (C2H4O) is initially contained in a rigid container at a total pressure of 760 mmHg absolute. The formation of ethanol occurs according to C2H4O + H2 C2H6O.
The nameplate on a 25-MVA, 60-Hz single-phase transformer indicates that it has a voltage rating of 8.0-kV:78-kV. A short-circuit test from the high-voltage side (low-voltage winding short circuited) gives readings of 4.53 kV, 321 A, and 77.5 kW.
Two line conductors carry currents of 1 A and 2 A respectively. The first conductor is on the x-axis, while the other is parallel to the y-axis, and passes through the point (0, 0, 1 m). Find all points on the z-axis such that Bx = -By.
