Finite Impulse Response Filters • • • Introduction to the z-transform Design and implementation of finite impulse response (FIR) filters Programming examples using C and TMS320C6x code The z-transform is introduced in conjunction with discrete-time signals. Mapping from the s-plane, associated with the Laplace transform, to the z-plane, associated with the z-transform, is illustrated. FIR filters are designed with the Fourier series method and implemented by programming a discrete convolution equation. Effects of window functions on the characteristics of FIR filters are covered. 4.1 INTRODUCTION TO THE Z-TRANSFORM The z-transform is utilized for the analysis of discrete-time signals, similar to the Laplace transform for...
