Using the DFT sequence X(k) for 0 ≤ k ≤ 5 computed in Problem 4.8, evaluate the inverse DFT for x(0) and x(4).
Problem 4.8
Given a sequence x(n), where x(0) = 0:8, x(1) = 0:6, x(2) = 0:4, and x(3) = 0:2 with two additional zero-padded data points x(4) = 0 and x(5) = 0, evaluate its DFT X(k).
Design a DC-coupled differential amplifier with differential gain of 50 for input signals near ground, supply voltages of +15V and -15V and quiescent currents of 0.1mA in each transistor.
A circuit consists of a current source, i=0.030 sin 500t, in parallel with L=20mH, C=50 micro Farads and R=25 Ohms. a. Determine the voltage V across the circuit. b. Solve for the power factor of the circuit.
A magnetic field of 2.0 T is applied to a bubble chamber to make the tracks of protons and other charged particles identifiable by the radius of the circles they move in. If a high-energy proton moves along an arc of a 3.3 cm circle
The other one is ON when the light sensor sees 10% more brightness than the left sensor. The third one goes ON if the brightness at the left sensor is in the range of -+10% of the right-light sensor.
Let D = 4xy ax +(2x2+2z2) ay + 4yz az nC/m2 and evaluate surface integrals to find the total charge enclosed in the rectangular parallel piped 0
A current source of 12 cos 2000t A, a 200-ohm resistor, and a 0.2-H inductor are in parallel. Assume steady-state conditions exist. At t = 1 ms, find the power being absorbed by the (a) resistor; (b) inductor; (c) sinusoidal source.
If gasoline has a 120,000 Btu/gal energy content, and an average tank fill up requires 15 gallons over a 5 minute period, what is the equivalent energy flow rate (or power) in Megawatts in chemical power flowing through the nozzle per fill up
Get digital still images and video sequences from the Internet, as needed. You can use color and/or gray-scale images. 2. Implement intra-frame DPCM . Start with a linear quantizer in the initial implementation.
It is required that you create a subroutine whose input is the pattern number to be displayed and whose output is the bit pattern needed to light the proper diodes.
A collimated light beam from a helium-neon laser at 632.8 nm wavelength impinges on a dielectric film of refractive index of 2.0 at an angle of 75 degrees to normal, with a polarization at 45 degrees to the plane of incidence.
The silicon substrate is N-type (doping level ND = 7x10^16cm-3), and the gate is heavily doped N+-type polysilicon. Assuming zero oxide charge density, determine the density of mobile charge at the semiconductor surface, if the voltage applied bet..
