Modulation transfer spectroscopy (MTS) has emerged as a pivotal technique in modern atomic physics and optical metrology. By utilising the nonlinear interaction between a modulated pump beam and an ...
FREQUENCY-MODULATION, or the technique of varying the frequency of radio waves for signalling purposes, has been known and used for many years ; but it was not until Armstrong in the United States in ...
Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...
