Develop a control system to fill a container with water after it is emptied through a stopcock at the bottom. The system must automatically shut off the water when the container is filled.
G(s)= K(s-2)(s-4) / s(s+5) Sketch the root locus and find the following: a) Break away and break in points b) The jw-axis crossing points c) The range of gain to keep system stable
A lighting load operates from a 208-V 60-Hz supply and is rated 1.0 kW with a power factor of 0.9 lagging. A 40-µF capacitor is connected in parallel with this load. Calculate the total power factor and the percent change in line current.
Design a CMOS Differential pair amplifier with a low frequency gain of at least 30dB, while driving a resistive load 50-ohm. The available circuit components are NMOS transistor, PMOS transistor, resistors, capacitors and inductors.
The angle of departure is defined as 180 degrees plus the phase angle of GH computed at the complex pole, but ignoring the contribution of that particular pole.
a) Find the general solution of the homogeneous ODE (the left hand side) and call it yh. b) Verify that yp= -0.5tcos(3t) is a solution.. i.e show that yp" + 9yp'= 3sin(3t). c) Construct the general solution of this ODE y=yh+yp
Find the total current I and the voltage across the capacitance. R = 420 ohms. capacitance = 292 ohms. inductance = 250 ohms. Source voltage 100 angle 0 degrees, 60 Hz.
A tank circuit coil is operating at a resonance frequency fres = 20 MHz; The circuit must operate with a bandwidth of 200 kHz. What is quality factor, Q, for the coil
aluminum has the FCC crystal structure. Its atomic weight is 26.98g/mole, and its density is 2.70g/cm3. Determine the atomic radius of a single aluminum atom.
An AC Voltmeter uses a bridge rectifier and 100 ohm PMMC which requires a 1mA DC current for full-scale deflection. Assuming ideal diodes, calculate the value of the multiplier resistor to obtain full scale deflection with 10 V AC applied to the i..
The silicon cube you were shown consisted of 4x4x4 unit cells. You were shown one dopant in the silicon cube. Given that the lattice constant of silicon is 0.543 nm. Calculate the dopant density represented by the 4x4x4 silicon cube simulation.
For each one of the 3 frequency responses, H(f), in parts (a), (b), and (c) do the following: i. Obtain the system's impulse response, h(t). ii. Indicate if the system is BIBO stable or not, and state why. iii. Indicate if the system is causal or not..
The number of cell phones recycled or refurbished instead of being sent to landfills is increasing by about 30% per year since 2004. In 2008, 5.5 million cell phones were recycled or refurbished. (a) Find an exponential model for the situation desc..
