The Realization of Narrow Band-Pass characteristics Using Sampled Data Filters

Abstract

<p>This thesis presents the results of an investigation of an alternative technique for the realization of narrow band-pass filters. This technique uses N parallel connected RC time-varying networks. A comparison of the performance of the 3-channel sampled data filter and one using the technique of quadrature modulation is made with respect to overall system performance.</p> <p>Excellent agreement between the theoretical and experimental results are obtained for the band-pass characteristics. Design criteria are also presented in order to approach the ideal operation of an N-path sampled data filter.</p>
