design a DC power supply with an ouput voltage of 12 v from an Ac source of120 v rms and 60 HZ. the rms ripple voltage should be limited to10% of the DC output. use a load resistance of 10 KΩ
Design a four pole lowpass filter with Sallen-Key topology and a Butterworth characteristic. The cutoff frequency of the filter must be 16 kHz.
Identify the bus types and the unknown variables of the power flow problem. Write the complete set of equations needed to solve the load flow problem.
Using Euler's relation , the signal x(t) defined above canbe expressed as a sun of complex exponential signals using the finite Fourier synthesis summation. Determine values for f, N and all the complex amplitudes, a.
where the assigned loop current leaves the voltage source. If current leaves the voltage source at its positive terminal, the voltage would be positive and if it leaves the voltage source at its negative terminal,the voltage would be negative.
A straight conducting wire of radius α isparallel to and at height h from the surface of the earth. Assuming that the earth is perfectly conducting, determine the capacitance and the force per unit length between the wire and the earth.
For each of the following functions, put the equation in the form of a Shannon decomposition. Create a pass transistor schematic to implement the function. Count the number of NMOS and PMOS transistors and the number of inverters.
Analysis of link budget DTH QPSK Satellite link, A direct-to-home satellite television system uses a geostationary satellite in orbit above the equator at a longitude of 109 degrees west.
If the power of a 500-kHz transmitter is increased from 150 W to 300 W, what would be the percentage change in field intensity at a given distance from the transmitter. What would be the decibel change in field intensity.
A 100 Hz electromagnetic wave is propagating down into the sea water with an electric field intensity of |E| = 1 V /m just beneath the sea surface. What is the time-average Poynting power density at a depth of 100 m
If we use the PC-relative addressing mode, and want to allow control transfer between instructions up to 50 locations away, how many bits of a branch instruction are needed to specify the PC-relative offset
A thermal oxide of thickness 120 nm needs to be grown on a silicon wafer (100) in dry oxygen. If the process integration issue requires having a temperature not higher than 1050 degreeC, determine the time required to obtain the desired thickness.
A self-excited DC shunt generator is delivering 20 A to a 100-V line when it is driven at 200 rad/s. It is known that Ra=1.0 ohms and Rf=100 ohms. When the generator is disconnected from the line, the drive motor speeds up to 220 rad/s
