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 ...

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 ...

The various methods for converting analogue signals into the form of pulse-code modulation and back again are reviewed. Reasons are given for preferring a particular method of conversion called ...

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 ...

The circuit to create waveform like this is based upon a simple relay that is driven by a clock signal.
