5.11 Refer to the contraharmonic filter given in Eq. (5.3-6).
(a) Explain why the filter is effective in eliminating pepper noise when Q is positive.
(b) Explain why the filter is effective in e

4.4 Consider the continuous function f(t)=sin(2nt).
(a) What is the period of f(t)?
(b) What is the frequency of f(t)?
The Fourier transform, F(), of f(t) is purely imaginary (Problem 4.3), and
4.17 You can infer from Problem 4.3 that 1 (,) and (t,z) 1. Use the first of these properties
and the translation property in Table 4.3 to show that the Fourier transform of the continuous function
f(t,z) = sin(20t + 20z) (there is
