Abstract
A signal processing apparatus and method extend the frequency response of a component whose output decreases past a first frequency. The apparatus responds to a signal having a range of frequencies which is applied to a component transmission line and the component transmission line is coupled to the component. The component transmission line is resonant at a second frequency greater than the first frequency and has a source impedance and an input impedance which are not matched. The source impedance is greater than the impedance of the component. The method comprises providing a signal, forming a transmission line which is resonant at the second frequency and coupling the transmission line to both the component and the signal source. The source impedance is adjusted such that the voltage across the component at a low frequency limit is about equal to the voltage across the component at the second frequency.
