Arduino Baud Rate Explained
In our earlier article, we have explained Basics of Serial Communication. Baud is the unit for the symbol rate in telecommunications. 1 baud is the speed when 1 symbol is transmitted per second. Each symbol corresponds to a defined, measurable signal change in the physical transmission medium. The baud rate of a data transmission must be the same on the sending and receiving sides. If the … [Read more...]
What is a Codec?
A codec is a pair of algorithms that digitally encodes and decodes data or signals. When converting directly from one format to another (e.g. MPEG-2 to MPEG-4 or MP3 to WMA) is called conversion or, in the case of audio and video files, transcoding. Colloquially, the use of the term codec has also become established for the integrated circuits that do the coding. In most cases, the analog … [Read more...]

Standard Data Streams – stdin & stdout
The standard streams are three data streams for input and output in the Unix operating system or related operating systems. They are also supported by the C standard library. Many programs automatically use the default input or output if no input or output files are specified on the command line. Data streams are a continuous flow of data sets, the end of which is usually not foreseeable in … [Read more...]
