Nyquist & Intermediate Frequency Recording:

A Discussion of Wideband Systems Implementation and Comparison of Under- and Over-sampling Techniques

Over the last fifty years, we have undergone incredible changes in the data recording arena. From post-detection, post-decision recording with reel to reel magnetic tape, to using the ubiquitous Chapter-10 digital recorders with many gigabits of bandwidth to record pre-detected data. This paper examines this latest technology implementation … using the Nyquist-Shannon’s Theorem to under-sample high-frequency data and compare the results.
