Received Oct 16, 2017 Revised Dec 12, 2017 Accepted Jan 4, 2018 Filter is one of the key components of all signals processing elements. Both the FIR and IIR filter are used to reduce the unwanted signal in the original signal. Here discussing the FIR filter and design the efficient FIR filter using Dual Ripple Carry Adder (RCA) based SQRT-carry select adder (CSLA). Many components present in th...
Abstract Dual media sand filters at Henriksdal WWTP began to show high head loss after five years of operation, especially during the fluidization for sorting filter bed backwashing. At that time, were still clean and dynamic loss, due clogging with suspended solids a cycle had its lowest value. Dynamic over lower layer surface in dual was detected some cycles operation. The initial has increas...
Background and purpose: Dual-energy mammography is a technique which is used to enhance the accuracy of breast cancer diagnosis especially in dense breasts. This study was conducted based on the simultaneous use of two contrast agents for automatic separation and also to evaluate their accuracy using dual-energy digital mammography. Materials and methods: A breast phantom was designed and b...
آلتراسوند یکی از روش های تصویربرداری است که هیج ضرری برای بدن ندارد، بنابرین نسبت به سایر دستگاه های پزشکی از محبوبیت و کاربرد بیشتری برخوردار است. طراحی بورد front-end یکی از چالشهای بزرگ در طراحی دستگاه سونوگرافی است که در آن سیگنالهای مدوله شده از بدن با دامنه بسیار کم باز می گردند که می توانند در رنج فرکانسی 2 تا 12 مگاهرتز کار کنند. تکنولوژی روز سعی در کوچک کردن مدارهای الکترونیکی و کمینه ...
This paper presents two novel dual-mode dual-band bandpass filters (BPFs) by using stubs loaded coupled line. The analytical equations of their transmission poles and transmission zeros are given by the classical even-/odd-mode method. Design rules for two dual-band BPFs are also given, which show the easily tuned passband frequency locations and in-band performance. As examples, two dualmode d...
