Consider the LTI described by the following input-output relation:y[n] = 3/4y[n-1]-1/8y[n-2]+x[n]
a)Find system function H(z) and check is system is stable.
b)Determine impluse response h[n] of system
c)Determine the step response s[n] of the system
d)Compute h[n] and s[n] for 0<= n<=10 using (b) and (c).
Why Can Discrete-Time FIR Digital Filters be a Linear Phase, Why can discrete-time FIR digital filters be made exactly linear phase, whereas IIR digital filters cannot?
Describe the steps in the keypad polling routine. Draw a flow chart for the keypad LCD software code. Discuss challenges experienced in developing the keypad LCD software code.
One reason that the maximum electric field is important is because of the possibility of impact ionization, which may be desired or undesired in a particular application. The process of impact ionization is dependent on the electric field
Calculate the de Broglie wavelength, for: (a) An electron with kinetic energy of (a) 1.0 eV, and (ii) 100 eV. (b) A proton with kinetic energy of 1.0 eV. (c) A singly ionized tungsten atom with k in.
the total amount of electricity that could potentially be generated from wind in the U S has been estimated at 10.8*10^9 Mw-hr annually , if one tenth of this potential is developed, estimate the number of 2 Mw windmills
Suppose station A and B are interconnected through two parallel unreliable links, where each link has a failure probability of 0.1. Calculate the average seconds per day when A and B lose communication.
g. What happened to all the power delivered to the resistors h. If the resistors are available with wattage ratings of 1/2 W, 1 W, 2 W, and 5 W, what minimum wattage rating can be used for each resistor
If it takes 1 sec to rotate 45 degrees after starting from rest, how long in seconds would it take to instead rotate 81 degrees after starting from rest under the same constant angular acceleration.
A 3-phase 230 V, 9 kVA, 0.9 PF (lagging) load is supplied by 10 kVA, 1330/230 V, 60 Hz three-phase transformer connected in Y-?. The equivalent impedance of transformer referred to the low-voltage side is 0.12 + j0.25.
Make a table showing Temperature as a function of pressure for Psat from 20 to 600 psia every 20 psi, and another table showing pressure as a function of temperature from 150 degrees to 350 degrees every 20 degrees.
The amplitudes of two signals X and Y have joint pdf: fXY (x,y) = e^(-x/2)*y*e^(-y^2) for x>0 , y>0. (a) Find the joint CDF (b) Find P [sqrt(x) > y] (c) Find the marginal PDFs (d) Determine if X and Y are independent.
