Perhaps the simplest approach to FIR filter design is to take the ideal impulse response hd[n] and truncate it which means multiplying it by a rectangular
Eigenfilters: A New Approach to Least-Squares FIR Filter Design
For example Nyquist filters can be easily designed using this approach. The design time for the new method is comparable to that of Remez exchange techniques.
Analysis of FIR Filter Design Techniques
FIR filters. In the paper the windowing method the frequency sampling methods and optimal filter design methods are discussed.
FIR Filter Design via Spectral Factorization and Convex Optimization
As a result we can solve them efficiently and globally by recently developed interior-point methods. We describe applications to filter and equalizer de- sign
