1.The original source information can be in analog(continuous)form,such as the human voice or music,or in digital(discrete)form,such as binary-coded numbers or alphanumeric codes.
1.原始的信息源既可以是模擬（連續(xù)）的，例如語(yǔ)音或音樂(lè)；也可以是數(shù)字（離散）的，例如二進(jìn)制編碼數(shù)或字符碼。

2.The signal-processing block at the transmitter conditions the source for more efficient transmission.
2.發(fā)射機(jī)中的信號(hào)處理單元對(duì)信源進(jìn)行調(diào)理，以便更有效地傳送。

3.The synchronization word reoccurs once again after the last channel has been received.
3.當(dāng)最后一個(gè)話路的碼字收到之后，同步碼字又再次出現(xiàn)。

4.In these descriptions we shall see how a speech channel of telephone quality maybe conveyed as a series of amplitude value,each value being represented,that is,coded,as a sequence of 8 binary digits.
4.在這些討論中，我們會(huì)看到話路中的語(yǔ)音信號(hào)是如何轉(zhuǎn)換成一個(gè)幅值序列的，而每個(gè)幅值又被編碼，即以8位二進(jìn)制數(shù)的序列表示。

5.If a universal microprocessor solution existed with which every design could realized,the electronics industry wouldn't be a very competitive place.
5.假如存在可用以實(shí)現(xiàn)任何設(shè)計(jì)的通用微處理器的話，電子行業(yè)就不會(huì)競(jìng)爭(zhēng)得如此激烈了。

6.One way of creating fusion here on earth is to heat and compress pellets containing hydrogen to the temperatures and pressures needed to fuse the nuclei of the hydrogen atoms together,creating tiny hydrogen bombs and thus generating incredible power.
6.在地球上實(shí)現(xiàn)核聚變的途徑是對(duì)含有氫氣的氣團(tuán)加溫加壓，以達(dá)到使氫原子核聚變的溫度和壓力，制造小型氫彈，從而出現(xiàn)難以想象的巨大能量。
