Assume we have a 1D print pattern with a resolution (i. e., spatial sampling frequency) of 120 dots per cm, which equals approximately 300 dots per inch (dpi) and a total signal length of N= 2800 samples. Calculate the
i. Sampling interval [2]
ii. Physical signal length [1]
iii. The fundamental frequency of this signal (again implicitly assumed to be periodic) [1]
iv. Maximum frequency that can be represented by this signal without aliasing [2]
v. A 1D optical scanner for sampling film transparencies is supposed to resolve image structures
with a precision of 3,000dpi. What spatial distance (in mm) between samples is required such
that no aliasing occurs?
