The Design and Analysis of Single-bit Ternary Band-pass Digital Filter: Design and Analysis of Single-bit Ternary Band-pass Digital Filter

Abstract

Recently, various general purpose sigma-delta modulation based general purpose DSP algorithms have been reported that possess simpler multiplier complexity, lower power consumption and less chip area features .Here in exploration, our goal is to carry on designing a ternary-bit DSP algorithm in which significant design element is a sigma delta modulator. The formation sigma - delta (SDM) has an amount of very pleasant and attractive possessions and inborn linearity by reason of which extensively consumed in communication systems. Signal is sampled more than that of Nyquist rate commonly word used oversampling and classically have a very short word length (i-e one-bit, binary or ternary) in sigma delta modulation technique. In this paper the design and simulation of ternary Band pass digital filter using sigma-delta modulation done in Mat-lab at different over-sampling ratio and compare it to multi-bit Band pass digital filter.
