Testing audio systems
The author shows readers what kinds of tests need to be done on digital audio signals and the equipment needed
Digitizing audio
The world around us is analog. Our perception mechanism is also analog. Standard audio transducers, such as the microphone and the loudspeaker, are analog
MPEG editing
The original development of analog television was based on the concept of direct, real-time, on-air transmission of live programs and, occasionally, films.
The ATSC standard
In the 1980s, many interested parties began developing concepts of advanced television, or HDTV, geared at reproducing superior-quality 16:9 aspect ratio
Audio multiplexing
Combining multiple audio channels into a single stream is called multiplexing. It’s complex and requires careful planning. However, there are many solutions available, which the author reviews
Audio compression and noise
In a previous article, we discussed analog audio SNR concepts. As mentioned, the dynamic range is restricted at the top by clipping (THD 1 percent) and
Analog audio noise
Michael Robin shows readers how analog noise is detrimental to the encoding results and what steps they can take to remove the noise and maximize the signal quality
Audio signal distribution methods
Different concepts and solutions were developed on the two sides of the Atlantic, and today we still bear the consequences. The author discusses the power-matching concept and the voltage-matching concept
Digital video compression and noise
The key to efficient compression is noise reduction prior to the compression stage. Michael Robin shows readers how noise adversely affects compression and reveals tips to remove it
Carrying the bits
Michael Robin reviews digital platforms to transport data streams. He looks at system requirements and minimum performance levels
