求翻译：数字数字基带传输系统的输入端通常是码元速率为，码元之间的宽度为T的二进制（多进制）脉冲序列，用符号d表示。由于二进制，因此，习惯用d或j表示码元速率，用j表示码元之间的宽度。脉冲形成器的变换作用之一是把单极性码变换成适合于信道传输的码型是什么意思？

Digital baseband digital transmission system is usually the input symbol rate, symbol T between the width of the binary (ary) pulse sequence, with the symbol d is. As the binary, so the practice of using d or j denotes the symbol rate, with j the width between said symbol. Pulse forming device is to

Digital digital baseband transmission system Code is usually the input data rate is, yards $width is T between $2 to the metric system (More) Pulse sequence, with symbolic D said. Due to system 2, therefore, accustomed to using D J or J said yards dollar rate, use the width between $said Code. Pulse

The digital numeral baseband transmission system input end usually is the element speed is, between the element width is the T binary system (multiple system) the pulse sequence, indicated with mark d.As a result of binary system, therefore, the custom with d or the j expression element speed, expre

Digital inputs digital base band transmission system is usually code rate, width between code as t-binary (non-binary) pulse sequence, indicated by a symbol d. Due to the binary, so use d or j represents the symbol rate, j representing the width between code. Transform of pulse forming one is suitab

Digital digital baseband input terminus of transmission system yards of yuans of speed usually, the width between yard of yuan is two system (many systems) pulse arrays of T, are indicated by symbol d. Because of two system, so used to say code yuans of speed with d or j, express width of code betwe
