    调整pdf的边缘及其行间距大小。首先把pdf保存为图片,然后用此程序调整边缘或行间距大小,把修改后的图片重新整合成pdf。此软件的目的是为了kindle用户编写。因为kindle的屏幕有限,除去多余的边缘和行间距,可以使kindle读书效率更高,减少过多翻页操作。(Adjust the line spacing pdf and the size of the edge. First, save the pdf as a picture, and then use this procedure to adjust the size of the edge or line spacing, the re-integration of the modified images into pdf. The purpose of this software is to kindle the user to write. Because of the limited screen kindle, to remove the extra edge and line spacing can make reading more efficient kindle, to reduce excessive flip operation.)

    数字调制就是把数字基带信号的频谱搬移到高频处,形成适合在信道中传输的带通信号。基本的数字调制方式有振幅键控(ASK)、频移键控(FSK)、绝对相移键控(PSK)、相对(差分)相移键控(DPSK)。在接收端可以采用想干解调或非相干解调还原数字基带信号。 (Digital modulation is the spectrum shifting to high frequency digital baseband signals, suitable for the formation of bandpass signal transmission in the channel. Digital modulation basic amplitude keying (ASK), frequency shift keying (FSK), the absolute phase shift keying (PSK), relative (differential) phase shift keying (DPSK). At the receiving end can be used to dry the demodulation or non coherent demodulating the digital baseband signal. )
