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. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJF 1277-2011_English be delivered?Answer: Upon your order, we will start to translate JJF 1277-2011_English as soon as possible, and keep you informed of the progress.
