The input to a filter is a discrete-time, zero-mean, random process whose autocorrelation function is
for some constant such that We wish to filter this process so that the output of the filter is white. That is, we want the output, to have an autocorrelation function,
(a) Find the transfer function of the filter. You may express your answer in terms of either a DTFT or a z-transform.
(b) Find the impulse response of the filter. For both parts, make sure your answer results in a causal filter.
Determine the ROM size and contents to implement a function which converts a sign and magnitude number from -5 to +6 to two's complement format.
What effect would the signal source impedance have on the non-inverting amplifier?
A container with a plunger compresses one pound mole of an ideal gas from 1 atmospheres pressure to 10 atmospheres. Calculate the amount of work done if the process is considered to be polytropic.
Draw a set of coordinate axes, and plot the locations of si(t) , i = 0; 1; 2; ... ; 7, after expressing each one as a generalized Fourier series in terms of the basis set found in part (a).
A combinational logic circuit has four imputs (A, B, C, and D)and one output Z. The output is 1 iff the input has three consecutive 0's or three consecutive 1's. Fore example, if A= 1, B = 0, C = 0, and D = 0, then Z = 1, but if A = 0, B = 1, C =0..
Write a program which uses 8 DIP switches on LAB PRO Board as 8 different speeds for motor. Each switch will run the dc motor at certain speed.
Each phase of a delta-connected load comprises a resistance of 30 and an 80 μF capacitor in series. The load is connected to a 400 V, 50 Hz, 3-phase supply.
Charged line and multiple conducting planes. An infinitely long line charged with a charge density PI is located at a distance d from a very large conductor, as in Figure 5.38.
To what minimum resistance value can the rheostat be set without blowing the fuse?- Assume a lamp resistance of 20 ohms.
Design a first-order digital highpass chebyshev filter (.5-db ripple) with a cutoff frequency of 850 Hz and a sampling frequency of 10 kHz. Determine the transfer function using BLT.
Design and sketch a band pass filter consisting of an RC high-pass filter with a cutoff frequency of 300 Hz and an RC low-pass filter with a cutoff frequency of 700 Hz. Carefully select the R and C of each filter so that one filter does not load t..
Two rolled-steel channels are to be welded back to back and used to support the loading shown. Knowing that the allowable normal stress for the steel used is 30 ksi, determine the most economical channels that can be used.
