A causal 4th order FIR digital filter, where its impulse response is symmetrical about its mid-point, has the following 3 values of the step response (i. e., the input is a step u(n)): y(n)=box(n)+b1x(n-1)+b2x(n-2), b3 x(n-3)+b4x(n-4), bo=0.02840647, b1=0.23700868, b2=0.469170166, b3=-.734585316, b4=0 y(0) = 0.02840647, y(1) = 0.26541468, and y(2) = 0.734585316. M) Determine the impulse response h(n). Is the filter stable?
N) Write an expression for the frequency response H(ejw). Hence, plot the magnitude and phase response. Identify the type of filter it represents?
0) Determine the difference equation of the system?
P) Draw the block diagram of the difference equation of the filter. How many multiplications and additions do we need for each sample?
Q) Determine the steady-state output yss(n) if the input signal is given by: x(n) = 10u(n) + 5 cos(0.5tn)u(n).

Excerpt from the ultimate fighting championship mary o'dell 1 american interest in mixed martial arts is growing. both male and female athletes are invited to compete, although this sport is not recommended for the prima donna. this full contact fighting combines various martial arts techniques so fighters with different styles can compete against each other. this intriguing sport has convinced more than one athlete that he is not, in fact, the alpha and the omega! many people think that all combative sports should be strictly monitored and regulated by state commissions. it is obvious that the ultimate fighting championship (ufc) is an organization that promotes combative athletic events. state athletic commissions should strictly monitor and regulate the ufc.select the rebuttal statement that best refutes the viewpoint in section one. a) it is necessary to oversee the athletes involved in mixed martial arts. b) it is unnecessary to oversee the athletes involved in mixed martial arts. c) it is necessary for athletes involved in mixed martial arts to self-regulate. d) one distinctive feature of mixed martial arts is the combination of various techniques.

Read this passage from geoffrey lean’s “one poor harvest away from chaos”: on wednesday, the food and agriculture organisation (fao) reported that global food prices has hit a record high and were likely to go on rising. . that is bad enough for britain, adding to the inflationary pressures from the soaring cost of oil and other commodities, not to mention the vat increase. but for the world’s poor, who have to spend 80 percent of their income on food, it could be catastrophic. why is the passage an example of deductive reasoning? a. the author is appealing to the feelings and emotions of the audience b. the author starts with specifics, using them to probe a general point. c. the author is starting with a general topic and moving to more specific information d. the author is showing that he biased against poor people
