The Nyquist–Shannon sampling theorem is a theorem in the field of signal processing which serves as a fundamental bridge between continuous-time signals and discrete-time signals. It establishes a sufficient condition for a sample rate that permits a discrete sequence of samples to capture all the information from a continuous-time signal of finite bandwidth. how invasive is an appedectomy

The conditions of the sampling theorem are met since the sample rate is well above twice the maximum (and in this case only) frequency of the signal. Figure 1 shows one period of this sine wave with the sample points marked as red circles.
