What is the basic concept of Fourier theory as it relates to real-world signals? How does the transfer function of a filter relate to this concept?
A bus in a balanced three-phase power system has a three-phase capacitor bank that supplies 1200 kVAR. In parallel with the capacitor bank is a three-phase load that draws 3500 kW at a power factor of 0.707 lagging.
A coil with impedence 8+j6Ω is connected in series with a capacitive reactance X. The series combination is connected in parallel with a resistor R. given that the equivalent impedence of the resulting circuit is 5/_0'Ω, find the value of R and X.
Discuss how delay is generated (1) using only one register, and (2) using a pair of registers . explain the method to calculate the delay time. Describe the interface connections of a 7 -segment display, which can display alphabets as well as dig..
The objective is to design a discrete common-emitter amplifier, the common-emitter amplifier is to have the following specifications: single ended input and output Av approximately 20 in the midband 3-dB bandwidth extending from 10 Hz
Find values of the intrinsic carrier concentration ni for silicon at -70, 0, 20, 100, and 125 °C. At each temperature, what fraction of the atoms is ionized. Recall that a silicon crystal has approximately 5×1022 atoms/cm3.
The PMAC motor is driving a purely inertial load. A constant torque of 5 Nm is developed to bring the system from rest to a speed of 5,000 rpm in 5 s. Neglect the stator resistance and the leakage inductance.
Nanowire with square cross-section: Starting with the time-independent Schrodinger equation: (a) use separation of variables to obtain three ordinary differential equations (ODEs) (b) solve the ODEs and obtain the solution that satisfies the boundary..
Suppose the one dimensional field A=Kx.ax exist in a region. Illustrate the validity of Gaussian theorem by evaluating its volume and surface integrals inside and the rectangular parallelepiped bounded by surface: x=1,x=4,y=2,y=-2,z=0,z=3
x[n] is the input sequenceapplied to a digital filter whose impulse response h[n] is alsogiven below. Find the resulting output sequence,y[n]. Hint: There's a VERY easy way to solve thisproblem, and a way which is not so easy. If it seems hard,you..
1) What are some practical op-amp applications Can you give example and explain why the bop-amp was used in your example 2) What is the most common used op-amp in the industry
An FSK system with Rb = 110bits/sec is transmitted over an RF Channel with white noise. The receiver uses non-coherent detection. If Eb/N = 5dB, evaluate Pb for this system.
1- Derive the transfer function of a third orderlow Pass Butterworth filter for a bandwidth of200 rad/sec. 2-Draw a simulation diagram for the design of this filter. Use integrators, amplifiers and summers.
