Question

Problem2 (a) Suppose the input sequence x[n] - cos(an) is applied to an FIR filter. With the proper choice of filter coefficients bk it is possible for the filter to produce y[n] = cos(2 true | false. n) (b) A filter has the frequency response H(e)- 22e-20. The filter's gain at the maximum possible frequency is The frequency response of a filter may be found by evaluating the system function at which part of the z-plane? (c) (d) Imagine a pole-zero diagram for the system function H(z). How would you draw the pole-zero diagram for its inverse filter H(z) 1/H(z)? (e) What feature of a pole-zero plot instantly tells you that the filter is FIR? (f) The acronym "IR" is often expanded as "Infinite Impulse Response." What specifically about the impulse response of such a filter is infinite? () A discontinuity in the plot of angle response H(e) is a sure sign that a system does not have linear phase[ true I false]. (h) MATLAB prints when you enter 1 : 2 : 6. () MATLAB prints when you enter [1 2 31 12 3 41 G) MATLAB: Given a true-color image stored in the variable img, write a code fragment to display the red color plane of img in a figure window:

Explanation / Answer

(a)

The filter can select the frequencies in the original signal. It doesn't have ability to produce new frequencies.

The answer is FALSE
