摘要： Described in embodiments herein are techniques for realizing filters having a variety of frequency responses, such as multiple pass-bands, high out-of-band rejection, without complicated designs. In accordance with an embodiment, a feedforward filter includes a first path, at least one second path and a signal combiner. The first path has a first translational filter, and employed for providing a first frequency response and generating a first output in response to an input signal based on the first frequency response. The at least one second path has a second translational filter and is coupled to the first path. The at least one second path is employed for providing a second frequency response that is different from the first frequency response to the input signal, and generating at least one second output in response to the input signal based on the second frequency response. The signal combiner is coupled to the first path and the second path, and employed for combining the first output and the at least one second output to generate a filtered signal.
