The sum of two independent random sequences with autocorrelation functions
is input to an LTI filter.
(a) Determine the Wiener smoothing filter. That is, find the impulse response of the filter which produces an output which is an MMSE estimate of S[n].
(b) Find the PSD of the filtered signal plus noise.
(c) Find the input SNR and an estimate of the output SNR. Discuss whether or not the Wiener filter improves the SNR.
a. Given a circuit with a VCVS (A=1000) in series with a 100K ohm resistor, convert this circuit to a VCCS in parallel with a resistor R. b. Connect both circuits to a 25K ohm load resistor and show they produce the same behavior in the load resis..
Sketch the magnitude spectrum of x(t) showing proper values for the amplitudes
A voltage v(t) = 24cos(2000t-45°)V is applied across a parallel connection of a 5-kΩ resistor and a 100-nF capacitor. Find the steady-state current i_c(t) through the capacitor and the steady-state current i_R(t) through the resistor.
MOS (p and n) npn and pnp transistors with parameters given in the text or select your own by using industrial data sheets, available on the internet. Also resistors, capacitors, and power supplies (10 V, 5 V, and 3.3 V) are available.
For each of the following systems with input x(t) and output y(t), state whether or not the system is (i) Linear and (ii) Time Invariant. Note that x(t) could be any complex valued signal. (a) y(t) = a^2 x(t), where a is a complex number.
A large reel of paper installed at the end of a paper machinehas a diameter of 1.8m, a length of 5.6m and a moment of inertia of4500 kg-m2. It is driven by a directly coupled,variable-speed DC motor turning at 120 rpm. The paper is kept undera con..
a machine processor address a maximum 2^24 bytes of memory. What is the maximum number of 32 bit words that can be store in memory.
You need to write a term paper based on this paper topic "Critical Coupling and Its Control in Optical Waveguide-Ring Resonator System"
Design a linear unregulated power supply that will provide an average of 500mA to a load at 15 volts average. Use a 12.6 VRMS sinusoidal source.
Problem 1: It is desired that an Arduino along with an EduShield be used to control 6 camerassimultaneously. Each is made by a dierent company: a Canon, a Nikon, an Olympus, a Pentax,a Sony, and a Minolta.
When carrying out an FFT of a cosine wave whose frequency is 0.1Hz and whose amplitude is unity , explain why the peak amplitude measurement obtained in the range 0.09Hz to 0.11Hz should be 0.5
Bicycle Rack When a full design specification was produced and the weighted objective procedure carried out, it was found that a tow bar mounted rack was the best solution. This would bolt to the tow bar once the tow ball has been removed.
