摘要: A linear -filter includes an input node to receive X-bit digital representation of a signal be filtered; output B-bit filtered signal; N-bit delay line having coupled the and N outputs; lookup table stored in storage device address inputs outputs B bits node. The represents mapping between individual ones representations corresponding linearly signal. ROM-based FIR filter for transmitter cellular telephone is one non-limiting embodiment this invention.
