WebOct 7, 2016 · Nyquist’s work states that an analog signal waveform can be converted into digital by sampling the analog signal at equal time intervals. Even today as we digitize analog signals, Nyquist's theorem is used to get the job done. Here’s to the science that keeps us connected. WebIn the beginning of his paper Shannon acknowledges the work done before him, by such pioneers as Harry Nyquist and RVL. Hartley at Bell Labs in the 1920s.
