IIR filters are digital filters with infinite impulse response. Unlike FIR filters, they have the feedback (a recursive part of a filter) and are known as recursive digital filters. Figure 2 Block diagrams of FIR and IIR filters For this reason IIR filters have much better frequency response than FIR filters of the same order. Unlike FIR .

ror (QMF) filters, IIR-QMF filters, Pseudo-QMF filters and nonlinear phase time- reversed QMF filters. Emphasis is given to nonlinear phase time-reversed QMF filters since they can be designed to remove all three types of distortion from the reconstructed signal. These filters are designed using the McClellan-Parks algo- rithm.

domain to obtain a digital filter that meets the specifications. The commonly used analog filters are 1. Butterworth filters - no ripples at all, 2. Chebychev filters - ripples in the passband OR in the stopband, and 3. Elliptical filters - ripples in BOTH the pass and stop bands. The design of these filters are well documented in the literature.

In contrast to IIR filters, FIR filters have a linear phase and inherent stability. This benefit makes FIR filters attr active enough to be designed into a large number of systems. However, for a given frequency response, FIR filters are a higher order than IIR filters, making FIR filters more computationally expensive. Figure 1 1.

The following slides describe the regular polyphase filter bank, the transpose form FIR filter, and optimizations based on symmetry This is a symmetric FIR filter, i.e., the first n/2 and the last n/2 coeffs are the same, albeit in reverse order. We can exploit this symmetry to implement an optimal form of the filter bank, using resource sharing.

I. INTRODUCTION Nonlinear methods in signal and image processing have become increasingly popular over the past thirty years. There are two general families of nonlinear filters: the homomorphic and polynomial filters, and the order statisticand morphological filters [1]. Homomorphic filters were developed during the 1970's and obey a

Digital filters play a significant role in signal processing. Due to the advent of digital signal processing (DSP) techniques, there is a strong need to design and develop efficient digital filters. In this context, a large number of research papers appear each year with continuous perfection in the digital filter design methods.

FIR Filters Digital FIR filters cannot be derived from analog filters - rational analog filters cannot have a finite impulse response. Why bother? 1. They are inherently stable 2. They can be designed to have a linear phase 3. There is a great flexibility in shaping their magnitude response 4. They are easy and convenient to implement

Chapter Two first discusses the need for an adaptive filter. Next, it presents adap-tation laws, principles of adaptive linear FIR filters, and principles of adaptive IIR filters. Then, it conducts a survey of adaptive nonlinear filters and a survey of applica-tions of adaptive nonlinear filters. This chapter furnishes the reader with the necessary

CHAPTER TWO BACKGROUND 2.1 IIR Digital Filters The analysis of roundoff noise for IIR filters proceeds in the same way as for FIR filters. The analysis for IIR filters is more complicated because roundoff noise computed internally must be propagated through a transfer function from the point of the quantization to the filter output.

8-bit MCU can process data in real-time for FIR filters and Goertzel Algorithms for DTMF decoding and implement a full FFT. 2. Digital FIR Filters Filters have many applications, including narrowing the input waveform to a band of interest and notching out undesired noise. Digital filters have some benefits over their analog counterparts.

Comparison between IIR and FIR Filters Comparing the IIR and the FIR filters, neither has a definite advantage: IIR filters are implemented more efficiently than FIR filters in terms of number of operations and required storage Implementation of an IIR filter using the difference equation resulting from its transfer function is simple and
