Chapter 5 Design of IIR Filters
The most common design method for digital IIR filters is based on designing an analogue IIR filter and then converting it to an equivalent digital filter There are many classes of analogue low-pass filter such as the Butterworth Chebyshev and Elliptic filters The classes differ in their nature of their magnitude and phase responses |

INTRODUCTION TO DIGITAL FILTERS
1 A digital filter is programmable i e its operation is determined by a program stored in the processor\'s memory This means the digital filter can easily be changed without affecting the circuitry (hardware) An analog filter can only be changed by redesigning the filter circuit 2 |

What is a digital filter?
Digital filters are used for two general combined, and (2) restoration of signals (electronic) filters can be used for these superior results. The most popular digital chapters. This introductory chapter describes about each of these filters.
What is a general digital filter equation?
The general digital filter equation is shown in Figure 6.32 which gives rise to the general transfer function H(z) which contains polynomials in both the numerator and the denominator. The roots of the denominator determine the pole locations of the filter, and the roots of the numerator determine the zero locations.
What are the disadvantages of a digital filter?
Finite wordlength effects: Digital filters are subject to noises like ADC noise and roundoff noise that could lead to instability. Long design and development times: The design and development times for digital filters, especially hardware development, can be much longer than for analog filters. where ak and bk are the coefficients of the filter.
How does a DSP based digital filter work?
The buffer memory is then read at a rate which is compatible with the speed of the DSP-based digital filter. In this manner, pseudo-realtime operation can be maintained as in a radar system, where signal processing is typically done on bursts of data collected after each transmitted pulse.
