Abstract
A method of providing frequency dependent signal attenuation. An RF input signal is split into a first signal portion and a second signal portion. The first signal portion is discrete time filtered and bandstop filtered to provide a filtered signal portion. The second signal portion is applied to a component and a component output signal portion is received from the component. The component output signal portion is combined with the filtered signal portion to provide an RF output signal having frequency dependent attenuation.
