Real world signals are continuous in time and continuous in amplitude. In order to process these signals using digital systems, the signals have to be sampled in time and quantized to discrete amplitudes. Although in general both actions result in distortion of the original signal, the distortion resulting from sampling in time can be avoided. Quantization of the signal to discrete amplitudes always introduces errors.
