Consider the sequence
x(k) = cos(k pi /6).
Find the transfer function and the difference equation for a 2nd -order FIR filter that has unity d.c. gain, but for which the given input x(k) produces zero forced response. (Your filter will have a "notch" at the given frequency, and H(1) =1.)
Find the transfer function and the difference equation for a stable 2nd -order filter that has unity d.c. gain, but for which the given input x(k) produces a large forced response. (Your filter will have a lightly damped resonance at the given frequency, and H( 1) =1.) Plot the frequency response of each filter. Program the corresponding difference equations and plot the response of each filter to the input sequence
x(k) = cos(k pi /6) + 1.
Make sure the time-domain results are consistent with the frequency response plots.
A p-type wafer has a diffused Phosphorous n-type junction with a junction depth of 0.15µm. a) If the wafer (no pre-existing oxide) is to be oxidized at 1000 C for two hours to form a ‘dense.
A CS amplifier using an NMOS with gm = 3.8 mA/V is found to have an overall voltage gain of -16 V/V. What value should a resistance RS inserted in the source lead have to reduce the overall voltage gain to -8 V/V
Resistance of Headlights, A 24-volt automotive battery is connected to two headlights, such that the two loads are in parallel
A ‘c-core' inductor has a total air-gap length of 3 mm and a cross-sectional area of 100 cm2. Two coils are wound on the core - one of 500-turns and another of 250-turns. Assuming the iron reluctance, fringing flux and leakage flux to be negligibl..
(1) If you have a transformer that is not in a circuit, how can you tell/determine what the ratio is (2) How do you tell if a diode is forward or bias. How much voltage is assumed dropped across a forward biased silicon diode.
A south-facing collector at latitude 40%u25E6 is tipped up at an angle equal to its latitude. Compute the following insolations for January 1st at solar noon: a. The direct beam insolation normal to the sun's rays.
When the piston is at its bottom dead center, the gas is initially at 10 psig, 65°F, and 10.5 in 3 . After compression and when the piston is at top dead center, the gas is 180°F and occupies 1.5 in 3 . What would be the new pressure of the gas in..
Which of the following items is considered as a factor of production and which is considered as a raw material? In case you classify an item as a factor of production, identify the type of the resource.
The location of the zeroes in the spectrum suddenly changes to 5 kHz, 10 kHz, 15 kHz.... What parameter of the rectangular pulses has changed and what is its new value?
Find the dimension of the window, as measured at the top of the oxide, after ideal isotropic etching (i.e. no overetch). Draw a cross section of the window opening with the resist still on.
a 14-bit successive approximation adc is used to sample a signal that has a full-scale range of 8V and a clock frequency of 12 MHz and a jitter of 50ns.initially this is used without a sample and hold amplifier.
A metal plate is subjected to tensile stresses of sigma x = 21 ksi and sigma y = 17 ksi. The corresponding strains measured in the plate are Ex=920 µE and Ey=620µE. Determine Poisson's ration v and the elastic modulus E for the ..
