Abstract:
A method of setting filtering characteristic of a signal processing apparatus includes following steps: configuring a first signal processing path, included in the signal processing apparatus and electrically connected to a signal input port of the signal processing apparatus, to have a first filtering characteristic; and configuring a second signal processing path, included in the signal processing apparatus and electrically connected between the signal input port and the first signal processing path, to have a second filtering characteristic different from the first filtering characteristic. When an input signal received at the signal input port includes a first signal component with a first frequency and a second signal component with a second frequency, most of the first signal component is processed by the first signal processing path, and most of the second signal component is processed by the second signal processing path.
