pulse code

基本解释

Similarly, the introduction of voice encoding techniques using pulse code modulation contributed to the concept's evolution.
利用脉冲编码调制的话音编码技术同样也对这一概念的发展起了作用。

The audio data should be in a format understood by the headset (for example, A-law PCM [Pulse Code Modulation] format for the Sony headset).
音频数据应当是耳机可以理解的格式（例如，Sony 耳机的 A-law PCM [Pulse Code Modulation] 格式）。
Conclusion:Ultrasonic excitation of pulse code is helpful and therefore has a high specificity and sensitivity in the diagnosis of RA and OA.
结论超声激励脉冲编码技术是一项有价值的诊断技术，对RA和OA的诊断具有高度的特异性和敏感性。

Pulse-code modulation is simply a way of representing the analog electrical signal, in digital form.

While it's always hard to pin down the exact origins of an idea -- especially one like pulse-code modulation, where a number of parties were involved -- sifting out the large and significant contributions from the gold pan of history tends to bring up the same names time and again.

Shannon would also contribute to the further development of pulse-code modulation (along with Bell alumni Bernard M Oliver and John R Pierce) at around the same time, using technology that eliminated some of the issues (such as complex circuitry) from the earlier, but conceptually similar, implementation from Briton Alec Reeves in 1938.

脉冲编码
The system uses digital pulse code modulation to transmit the optical pulses information.
系统采用数字脉冲编码方式对控制系统的信号进行调制,将信息加载在光脉冲序列上发射出去。
