The meaning of PULSE is the regular expansion of an artery caused by the ejection of blood into the arterial system by the contractions of the heart. How to use pulse in a sentence.
Pulse code modulation (PCM) is a digital representation of an analog signal that takes samples of the amplitude of the analog signal at regular intervals. The sampled analog data is changed to, and then represented by, binary data. PCM requires a very accurate clock. The number of samples pe...
PCM(Pulse Code Modulation)脉冲编码调制,是将连续的模拟信号变换成离散的数字信号的过程,是模数转换的实例化,步骤包括采样、量化、编码。在调制过程中将模拟信号每隔一定时间进行采样,使其离散化,同时将采样值按分层单位四舍五入取整量化,同时将采样值按一组二进制码来表示采样脉冲的幅值。 1、采样—通常为8000Hz:...
PCM(Pulse-code modulation)脉冲编码调制 在音频处理中,我们会经常听到PCM数据,那么什么是PCM数据呢? PCM数据就是模拟信号经过PCM以后的数字信号,PCM就是把音频信号由模拟信号(时间连续,取值连续)转为数字信号(时间离散,取值离散)的过程。数字信号有很多优点,因此一般传输的信号都是数字信号。
抽样定理是任何模拟信号数字化的理论基础,PCM编码就是建立在抽样定理基础之上的,PCM编码主要包括抽样、量化、编码三个步骤。 (1)抽样:在满足抽样定理的条件下,每隔固定的时间间隔取出模拟信号的采样值,把连续时间的模拟信号转换成离散时间连续幅度的抽样信号。 (2)量化:将抽样取得的离散时间连续幅度的抽样信号转换成离...
