Abstract: The present invention documents a digital channelized receiver for signal intercept applications. A hardware efficient implementation of a uniform filter bank in which the number of filters, K, is greater than the decimation factor, M, is provided. By optimizing the filter bank frequency response, in conjunction with K and M, the proposed invention allows a simple channel arbitration logic to be implemented. In addition, the present invention provides reliable instantaneous frequency measurements and parameter estimates across the desired frequency range while reducing the data processing speed requirements by a factor of M.
