A problem was identified as being caused by the Canonical Signed Digit (CSD) generated during the calculation and selection of filter coefficients for higher-order FIR filters, as revealed by the study that was provided. It is also discussed how to use a second approach, known as canonical signed digits-based coefficients computation, which provides a distinct advantage in the overall process of developing, selecting, and executing FIR filters, while also being more energy efficient in terms of power consumption. A software tool called CSDFIR, which implements the recommended design technique, can be used to generate Chebyshev optimum floating point and fixed point CSD FIR filters.
