A band pass filter is implemented utilizing Channelized Active Noise Elimination (CANE) in combining Finite Impulse Response (FIR) filtering into a radio frequency (RF) transmitter, or transmission path. The FIR filtering is performed in a combination of multiple conversion paths of delay units, vector modulators and PAs so that the low pass characteristics of the FIR filter are upconverted on the adjacent frequency of the carrier to form a band pass filter at the output of the transmitter. Use of CANE avoids the need of high sampling rates, while also eliminating the need of either broad bandwidth delay lines or modulated power amplifiers. The technique is well-suited for suppression of the quantization noise generated in RF transmitters with bitstream modulations such as the Envelope Delta Sigma Modulation (EDSM).
