Abstract

The tools we have just developed (convolution and the Fourier transform for functions) are going to be used to study analog filters that are governed by a linear differential equation with constant coefficients,
$$\sum\limits_{k = 0}^q {{b_k}} {g^{(k)}} = \sum\limits_{j = 0}^p {{a_j}} {f^{(j)}},{a_p} \cdot {b_q} \ne 0,$$
(24.1)
where f is the input and g = A(f) is the output. Other conditions must be given to eliminate ambiguity among the possible solutions of (24.1).
