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 ...

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 ...

解 释: 一种新型的脉冲编码技术，它是利用自适应技术和差值编码技术相结合的一种编解码技术。可以使64 kbit/s的脉冲编码(PCM)信号进一步压缩为32 kbit/s的脉冲编码数据。使传输脉冲编码所需要的带宽减少一半，提高了信道的利用效率，并且还可以使脉码调制 ...

For technical and economic reasons, the present network of lines used for distributing sound signals to transmitters at audio frequencies will eventually have to be replaced by some telecommunication ...

Equipment is described which has been constructed for converting analogue television signals into 8-bit PCM signals and vice versa. The conversion rate used for video signals is approximately 13 ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

To analyse Msn2 and Mig1 dynamics in the same cell, we constructed strains expressing fusions of Msn2 and Mig1 proteins to the distinguishable fluorescent proteins 39 mKO2 and mCherry, respectively ...

Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method of generating a ...
