Digital instruments sample analog waveforms and operate on the samples with the assurance that the data can be restored to continuous analog form. The sampling theorem states that a signal digitized ...

Multi-rate processing and sample rate conversion, or interpolation and decimation as they re known, are a clever digital signal processing (DSP) techniques that broadband and wireless design engineers ...

Engineers are always looking to make their designs more efficient. Don has a DSP technique that should ease your computational burden. Interpolation and approximation are thorny issues for software ...
