Sources of noise generation are pervasive in contemporary industrial applications. Unwanted noise presents one of the major problems in measuring power or protecting circuits in such an environment. Knowing the characteristics and understanding t

This routine returns the coefficients of the 𝑁 -coefficient symmetric prototype filter 𝐻 (𝑧 ). The coefficients are normalized to have energy 1/2. When the analysis and synthesis filters are configured as shown above, the overall
