Patent ID: 8090114

Claim:
A convertible filter comprising: a first delay element; a first weighting element coupled to the first delay element to cooperate with the first delay element to enable the convertible filter to introduce a zero into a transform; a first power conductor coupled to the first delay element and the first weighting element to convey power to the first delay element and the first weighting element; a second delay element; a second weighting element coupled to the second delay element to cooperate with the second delay element to enable the convertible filter to introduce a pole into the transform; and a second power conductor coupled to the second delay element and the second weighting element to convey power to the second delay element and the second weighting element to enable power to be selectively provided to the second delay element and the second weighting element to enable the digital filter to be dynamically configured as either a FIR filter by not providing power through the second power conductor to the second delay element and the second weighting element or an IIR filter by providing power through the second power conductor to the second delay element and the second weighting element.
