Abstract:

Recently, renewed interest has been given to the use of N-path filters as an alternative method of realizing analog filters. The N-path filter is a configuration composed of N-parallel paths containing identical path filters flanked by input and output modulators. The design of an N-path filter requires that its periodic modulating functions provide a desired set of Fourier coefficients while the rest of the Fourier coefficients may be arbitrary. To illustrate this numerical method, three applications of the N-path filter that are of practical interest are considered A single passband filter A least mean-squared error filter A filter matched to a periodic input signal.
