In the present century, digital signal processing (DSP) approaches are considered to be one of the most powerful technologies which may shape the science and technology in coming decades. From 1970 onwards, a drastic revolution took place in a wider domain of DSP which has made it popular in several studies such as radar and sonar signal processing, digital televisions, wireless communication scenarios and other multimedia setup etc. Digital filters form the backbone of this DSP architecture and in point of fact the field of digital filter design has drawn justified recognition from the researchers throughout the world for the last 50 years. In connection to this, thousands of research articles may be found from the literature which had extensively addressed on the design of such filters. In order to meet the requirement of narrow transition-band, finite impulse response (FIR) filters are commonly assumed to be of higher order and accordingly it significantly enhances computational complexity. In regard to this, construction of hardware efficient digital filters had drawn significant consideration which aims to include minimum hardware elements during its application and consequently consumes less power. This review paper illustrates various techniques for the implementation of hardware efficient narrow transition-band FIR filter and investigates a number of favourable attributes which are capable in sustaining the stringent requirements of communication standards. A good number of relevant articles are taken from the literature so as to make a robust and complete review.

在本世纪，数字信号处理（DSP）方法被认为是最强大的技术之一，可能在未来几十年内影响科学技术。从1970年开始，DSP的更广泛领域发生了一场激烈的革命，使其在雷达和声纳信号处理，数字电视，无线通信场景和其他多媒体设置等多项研究中得到普及。数字滤波器构成了这一领域的骨干。在过去的50年中，DSP体系结构以及事实上的数字滤波器设计领域已经得到了全球研究人员的充分认可。与此相关，从关于这种滤波器设计的文献中可以找到成千上万的研究文章。为了满足窄过渡带的要求，通常假定有限脉冲响应（FIR）滤波器具有较高的阶数，因此它会大大提高计算复杂性。关于这一点，硬件有效的数字滤波器的构造已经引起了广泛的考虑，其目的是在其应用期间包括最少的硬件元件，因此消耗较少的功率。这篇综述文章阐述了用于实现硬件有效的窄过渡带FIR滤波器的各种技术，并研究了能够满足通信标准的严格要求的许多有利属性。从文献中摘录了大量相关文章，以便进行有力而完整的评论。
