2. (8 points) Fill in the blanks for the following statements: (a) A filter allows frequencies above a certain value. (b) An ideal sampling produces samples equivalent to value ofsignal at the desired points. c) The Fourier transform X(o) of a signal x(t) allows us to look at the (d) A signal can be uniquely recovered from its samples if (e) An image is a representation of a view of an object, where and y (f) The highest frequency of a band-limited signal is referred to as its frequency. of the signal. varies with coordinates x filters are implemented using circuit elements

Explanation / Answer

2: a) A high pass filter allows frequencies above a certain value

b) An ideal sampling produces samples equivalent to the instantaneous value of the continuous signal at the desired points

c) The fourier transform of a signal allows us to look at the spectrum of the signal

d) A signal can be uniquely recovered from its samples if band-limited
