Design Finite Impulse Response Digital Filters
This four-part article series draws to a close with a practical example of designing a multipart FIR filter to meet the spectral-mask requirements of GSM cellular systems.
Design Finite Impulse Response Digital Filters
The use of interpolation can save coefficients and required signal-processing power when implementing Nyquist FIR filters and multichannel filter banks.
Design Finite Impulse Response Digital Filters
Precise FIR digital filters can be designed with the help of a popular mathematical modeling program and an understanding of basic performance trade-offs.
Design Finite Impulse Response Digital Filters
Interpolated FIR filters can combine two designs to achieve a demanding set of performance specifications while at the same time conserving computational resources.
