Replace the cutoff frequency specification of Example 15.3 with ωC = 10 rad/s and determine the order of the filter required to achieve 40 dB attenuation at ωS = 24 rad/s.
EXAMPLE 15.3
Determining the Order of a Butterworth Filter Determine the required order of a filter, given the filter specifications
Two large flat charged plates are fixed parallel to one another in a large tank of distilled water (Er=81) with a total surface charge of 41.25×10-7 C on each plate (with opposite polarities). The plates are square, 4 m each side.
A zero mean gaussian random vector X=(X1, X2)T has a covariance matrix given by K=[ 3 -1 -1 3 ] Find a transformation matrix A so that the vector Y=AX is a gaussian random vector with uncorrelated (and therefore independent) components of unity va..
A sequential circuit for a luggage lock has 10 push buttons labeled0,1,2,3,4,5,6,7,8,9. Each pushbutton 0 through 9 produces a 1on X_i, i=0 through 9 with all other values on variable X_ j, jdoes not equal i, equal to 0.
The propagation law follows the free space up to a distance ofdbreak = 50 meters, and for larger distances the receive power is similar to(d/dbreak)-4.2. Transmit antenna gain is -7dB; the receive antenna gain is 9 dB. Compute the available fadi..
Determine the maximum stress in the blade, knowing that it is 0.018 in. thick and 0.625 in. wide. Use E = 29 X 106 psi.
Explain why learning reduces the effective marginal cost of production. If firms set prices in proportion to their marginal costs, as suggested by the Economics Primer, how can learning firms ever hope to make a profit?
Show that aliasing will occur if the signal y(t) = e^-t(sin)(2t) is sampled with T=0.2 by finding the z transform of the sampled sequence and then finding the inverse z transform.

Estimate the size and weight of an 1970 automobile using 1970 electronics technology which would have the equivalent computational power and electronics a typical 2013 automobile.
What explanation of the 8 pins of 555 Timer
A gasoline engine with an efficiency of 0.40 generates 1500 W of power. If a liter of gasolina has an energy content of 3.7 x 10^7 J, how many liters of gasoline does the engine consume each hour?
A switch with a single-bit output chooses which of the two 8-bit streams will be passed on a display's single 8-bit input. Create a circuit to connect the two video sources, the switch, and the display. Use at least one mux(a single mux or an N-bi..
