Wave is a very broad physical concept. In the field of electronic technology, "wave" is narrowly confined to describing the process of fluctuating the value of various physical quantities with time. The process is transformed into the time function of voltage or current through all kinds of sensors. It is called the time waveform of all kinds of physical quantities, or it is called signal. Since the time of the independent variable is continuous, it is called a continuous time signal and is used to call it a Analog Signal. With the emergence and rapid development of the technology of digital computer (generally referred to as computer), in order to facilitate the processing of signals by computers, a complete theory and method of transforming continuous time signals into discrete time signals under the guidance of sampling theorem are generated. That is to say, can only use the original analog signal samples in a series of discrete time coordinate values on the expression of the original signal without losing any information, wave, waveform and frequency of these concepts is the expression of a variety of changes since the objective physic |
