Filter design is one of the perennial topics in signal processing. FIR filters are often preferred for their simple implementation and robustness, so they are an appropriate subject for this first chapter devoted to applications. All the design methods presented here are based on positive ...
In Chapter 22, we considered two simple finite impulse response (FIR) filters. We have not yet considered how one goes about designing a generic finite impulse response filter. We now remedy that lack.Page %P Close Plain text Look Inside Other actions Export citation About this Book ...
A computer-aided technique for designing FIR digital filters with close to linear phase property is presented. The approach is based on a constrained optimisation problem designed to minimise the mean-square error between a desired response and the filter response over a passband of interest subject...
We will guarantee the optimality of the solution obtained. Hence, it is possible to obtain the optimal discrete coefficients. It is confirmed that the optimal coefficients of linear phase FIR filter with the SP2 coefficients could be designed fast with enough precisions by the computational ...

Finally, the degree equation of the filter is introduced. We present the design of 4 types of narrow band FIR filters: the maximally at notch FIR filter, the equiripple notch FIR filter, the equiripple DC-notch FIR filter and the equiripple comb FIR filter. Equiripple filters are optimal in...
As we saw in section 5.3, an FIR filter is easily constrained to have one of two particularly useful properties: namely, linear-phase or linear-plus-90°-phase response corresponding to even or odd symmetry, respectively, in its impulse response. Therefo
The filter has become an important device when people use for communication and deal with all kinds of signals. FPGA is very suitable for digital signal processing. And it is very good for designing digital filter by using FPGA. A FIR digital filter is designed based on FPGA in this paper,...
