Most signals of our interest -- wireless communication waveforms -- are continuous-time as they have to travel through a real wireless channel. To process such a signal using digital signal processing techniques, the signal must be converted into a sequence of numbers. This can be done through the process of periodic sampling. In this video, I talk about the implications of this process in digital domain. #communicationsystems #digitalsignalprocessing #wireless #digitalsystemdesign
