Sampling Theorems

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.
