What is sin x )/ x interpolation?
An oscilloscope's sample rate is often touted as a banner specification for the instrument; higher being better. In reality, as long as the rules of Nyquist are not violated, an oscilloscope can reconstruct a user's signal identically . This reconstruction process is often referred to as sin(x)/x interpolation.
What is interpolation in oscilloscope?
The generation of samples that occur in between actual waveform samples is called interpolation. When done properly, this results in a waveform with a higher resultant sample rate that is a closer approximation of the analog waveform under analysis.
