1. This article discusses the design of fractional delay filters, Nyquist filters, lowpass filters and diamond-shaped filters.
2. It establishes relationships between these different types of filters so that the design tools of one filter can be applied to design another filter.
3. It also presents several numerical examples to demonstrate the effectiveness of the proposed design methods.
The article is generally reliable and trustworthy in its discussion of the design of fractional delay filters, Nyquist filters, lowpass filters and diamond-shaped filters. The article provides a comprehensive overview of existing methods for designing these types of filters and establishes relationships between them so that the design tools of one filter can be applied to design another filter. The article also provides several numerical examples to demonstrate the effectiveness of the proposed design methods.
However, there are some potential biases in the article that should be noted. For example, it does not explore any counterarguments or present both sides equally when discussing existing methods for designing these types of filters. Additionally, it does not provide any evidence for its claims or discuss any possible risks associated with using these designs. Furthermore, some points may be missing from consideration as well as some evidence for its claims may be missing or incomplete.
In conclusion, while this article is generally reliable and trustworthy in its discussion of the design of fractional delay filters, Nyquist filters, lowpass filters and diamond-shaped filters, there are some potential biases that should be noted when considering its content.
