Design a combinational circuit that compares two 4-bit unsigned numbers A and B to see whether B is greater than A. The circuit has one output X, so that X = 1 if A < B and X = 0 if A >= B.
Compute the inverse Fourier transform for X(ω) = cos 4ω. 5. A signal with the highest frequency component at 10 kHz is to be sampled. To reconstruct the signal, the sampling must be done at a minimum frequency of?
In a simple model of the hydrogen atom an electron has a circular orbit of radius 5.0 x 10-11 m around a stationary proton.(a) the magnitude of the electrical force exerted by the proton on the electron, (b) the speed of the electron in its motion ar..
A point charge q resides in a 90 degree grounded conducting corner at the same perpendicular distance d from each conducting half-plane. Find the force on the charge caused by the induced surface charges.
find the received power (in W) if the transmitted power is 100 W, the distance of the dipole from the transmitting and receiving antennas is 100 m, the gain of the transmitting and receiving antennas is 15 dB each, and the frequency of operation i..
Approximation of quarter circle using Bezier curve, Determine the Bezier curve of order 3 that approximates a quarter circle centered at (0,0), (1,0), (0,1).
An Internet service provider has three different subscription packages for its customers: Package A: For $9.95 per month 10 hours of access are provided. Additional hours are $2.00 per hour. Package B: For $14.95 per month 20 hours of access are pr..
Use the simulation timing diagram to compare the worse case time to do an operation with your ALU with the worst case using the 74LS381. State which operation takes the longest and list the time required for both ALU's.
a) What is the minimum sampling frequency b) Specify the number of uniform quantization steps needed and the channel null bandwidth required, assuming that the peak signal-to-noise ratio at the receiver output needs to be at least 30 dB
Determine the period of a clock waveform whose frequency is: a. 2 MHz b. 500 kHz c. 4.27 MHz d. 17 MHz. Write the VHDL text file (Entity and Architecture) for a 2-input NAND gate. Write the VHDL text file for a 3-input NOR gate.
A certain amplifier has pole frequencies of f1=f2=f3=50MHz. The DC open-loop gain is 10^5. Find the pole frequency fc for the fourth pole so that the phase margin is 30 degrees for beta = 0.1 Also, find the corresponding gain margin.
An abrupt silicon pn junction at zero bias has dopant concentrations of Na = 1017/cm3 and Nd = 5 x 1015 cm-3 at T = 300K. (a) Calculate the Fermi level on each side of the junction with respect to the intrinsic Fermi level.
A shunt motor has the following ratings: 75 kW, 240 V, 1750 rpm, 300 A. The motor is supplied with 240 V source (constant) at its armature terminals. Its armature resistance is 0.0144 [O]. At rated current Ia = 300 A, the motor runs at rated speed..
