A project manager placed an order for ball bearings for some heavy duty manufacturing machinery. What is the surface area in square millimeters of one of these bearnings if it has a diameter of 0.4 inches
Semiconductor A has a bandgap of 2.5eV while semiconductor B has a bandgap of 1.5eV. What is the ratio of the intrinsic carrier concentrations in the two materials (niA/niB) at 300K
A 6-bit DAC has an input 1001012 and uses a 10.0-V reference.
Implement a multiple mode counter
What are the respective advantages and disadvantages of the asynchronous and synchronous communication modes from a reliability perspective?
Needs to oscillate 5 times per second. Amplitude envelope increases 25% every second. Amplitude is 1 at t =0. The derivative at t = 0 is 54.6371. the sinusoid has to be a cos(2*pi*5*t) for the exponential exp(at).
A bar phantom is imaged by an LSI system which is modeled as an ideal moving average system. The PSF of the system is h(x,y) = rect(x/delta, y/delta) (a) If bar separation of the bar phantom is f what is the output of the imaging system
The circuit will have as inputs a minimum of two inputs; the binary equivalent of two decimal numbers of not greater than (10,000)10. The circuit will also produce a minimum of two outputs, the quotient and the remainder.
An infinite grounded conducting tube of radius 10cm is centered on the z axis. A concentric charged tube of radius 6 cm has a surface charge density of 24 uC/m2. A 1m long section of the charged tube is compressed to change its radius to 3 cm.
Spectrum Analyzer, A spectrum analyzer is connected to an unknown signal. The spectrum analyzer displays the power level of signals in dBm vertically and frequency horizontally. The spectrum of the unknown signal creates the following display:
Find the magnitude of the electric field at all points in space both inside and outside the slab, in terms of x, the distance measured from the central plane of the slab. What is the field for x = 1.00 cm What is the field for x = 8.00 cm
Consider the following signal y[n]; y[n] = X1[n+3] * X2[n] The signals X1 and X2 are defined as X1[n]=((1/2)^n) u[n] X2[n]= ((1/3)^n u[n] Determine the Z transform of y[n].
