Patent ID: 7340019

Claim:
An apparatus, comprising: at least two convolver branches, wherein a first branch of the at least two convolver branches includes a first multiplier to multiply an input signal with a first multiplication value, a first filter to filter an output of the first multiplier, and a first sample and hold circuit to receive the output of the first filter to provide a first sampled output, and a second branch of the at least two convolver branches includes a second multiplier to multiply the input signal with a second multiplication value, a second filter to filter an output of the second multiplier, and a second sample and hold circuit to receive the output of the second filter to provide a second sampled output; and a multiplexer to combine the first and second sampled outputs; wherein the first sampled output is added to an input of the second sample and hold circuit and the second sampled output is added to an input of the first sample and hold circuit.
