In part 1, we started to make some intuitive connections between near-Nyquist sampling, the addition of close-frequency sines, and how those signals would interact with perfect LP filters. Let's put ...

Optical Nyquist pulse generation and transmission have emerged as pivotal technologies in the pursuit of maximising data throughput and optimising spectral efficiency in modern fibre‐optic ...

In “Why DAC and ADC responses droop,” we looked at the two common places where the sinc() function crops up in a data acquisition system. A DAC with zero-order hold has a frequency response that ...
