New Words dedicate:give, devote(one's time, energy, life, etc. to a noble cause or purpose If you dedicate yourself to something you decide to give a lot of time and effort to it because you think it is important

数字通信系统具有许多优点。然而许多信源输出都是模拟信号。 若要利用数字通信系统传输模拟信号,一般需三个步骤: (1)把模拟信号数字化,即模数转换(A/D); (2)进行数字方式传输; (3)把数字信号还原为模拟信号,即数模转换(D/A) 由于A/D或D/A变换的过程通常由信源编(译)码器实现,所以我们把发端 的A/D变换称为信源编码,而收端的D/A变换称为信源译码,如语音信号的数字 化叫做语音编码

Frequency response is the analysis of the response of systemswhen subjected to a sinusoidal change in input. When a linear system is subjected to a sinusoidal input, its ultimate response is also a sustained sinusoidal wave, with the same frequency. The figure below compares the output response of a system (solid line) with a sinusoidal input (dashed line) disturbing the system
