Download a local copy of the CentOS 7 repositories
Instructions for downloading a local copy of the CentOS 7 repositories. This is useful when you have an isolated development network or many local clients requiring updates.
Cascaded integrator–comb (CIC) filters
CIC filters are computationally efficient implementations of narrowband lowpass filters. They are particularly suited for use as an anti-aliasing filter when decimating or an anti-image filter when interpolating. CIC filters are well suited for implementation in FPGAs and ASICs as they only require addition and subtraction operations and not multiplication.
Using Git offline
Some companies use an isolated network or even the complete lack of a network as a security measure to protect from unauthorized access. Working on these systems can be a struggle but it is still possible, and perhaps even more important, to use a proper version control tool like Git.
