3 Terms and Definitions

3.1 symbol clock symbolclock In the synthesis and analysis of digital modulation signal, since the source signal is a digital modulation data bits, data bits It is the time discrete signal, and the actual transmission time is a continuous electrical signal. At the time of the establishment of discrete symbols connected Continued signal or a continuous signal analysis need to be converted into a discrete signal through the acquisition goes through the clock collection, Symbol clock signal is discrete and continuous signal conversion process clock signal. The accuracy of the signal on the modem Transfer accuracy has a decisive influence.
