Analog transmission is not particularly efficient. When the signal-to-noise ratio of an analog signal deteriorates due to attenuation, amplifying the signal also amplifies noise. Digital signals are ...

首先，我们要阐述一下PCM格式的DVD-Audio。PCM（Pulse Code Modulation，脉冲编码调制）是一个和DSD （Direct Stream Digital 直接数据流）对应的概念。DVD-Audio的核心技术就是PCM数字音频编码。PCM编码锁骨对模拟信号波形的各点进行数字取样进行编码。在还原过程中，PCM编码 ...

开博尔最新发布的Q50支持PCM 32bit/768kHz格式,但是很多新客户不明白这些数字是什么意思,我这里就为大家解答一下。 PCM(Pulse Code Modulation)也被称为脉冲编码调制,它是一种脉冲调制方式,先对信号进行周期的取样,再把每个取样进行量化,以数码方式进行传输。也就是将 ...

In MIPI Soundwire: Digital Audio Simplified, we mentioned that digital audio formats including Pulse Code Modulation (PCM) and Pulse Density Modulation (PDM) are target applications for MIPI Soundwire ...

The MAX98357A are digital pulse-code modulation (PCM) input Class D power amplifiers that provide Class AB audio performance with Class D efficiency. These ICs offer five selectable gain settings (3 ...
