Efficient structure for single-bit digital comb filters and resonators

A design technique for a single-bit digital comb filter is presented. The proposed filter response and performance are assessed in terms of signal-to-quantization-noise ratio (SQNR) and stability. It is found that the comb filter possesses a distinct frequency response in broadband signal applications. The same technique is utilized to design and simulate a single-bit N-period digital resonator. Feedback loop filters can be used to tune the frequency response of the
