WebOct 15, 2014 · Sampling Theorems. Periodic Sampling. Most signals are continuous in time. Example: voice, music, images ADC and DAC is needed to convert from continuous-time signals to discrete-time signals form and vice-versa. Periodic Sampling of an analog signal is shown below:. Periodic Sampling. WebFeb 28, 2024 · Suppose we sample an 8 kHz sine wave at the commonly used rate of 48 kHz. 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.
