SPDIF, or the Sony/Philips Digital Interconnect Format) is used to carry or transport digital audio signals in consumer electronic equipment such as CD and DVD players, PC audio cards, and car audio systems over short distances. The digital signal can be carried over fiber optic (TOSLINK connectors) or coaxial cable (RCA connectors) and is also …
TOSLINK or Toshiba – LINK is a connection standard for digital audio streams. It is a standard which uses fiber optic cables. The important feature of fiber optic cables is that they convert audio signals into light impulses as opposed to electric signals. TOSLINK cables usually transmit their signals as the red LED lights. The …
Experts in science and technology developed a known digital audio standard, AES/EBU, to handle signals from digital audio systems. It is known officially by the name AES3 and an Audio Engineering Society and the European Broadcasting Union developed it, hence the name. It was first publicized in 1989, but was revised later in 1995, 1998, …
The Need for Wireless Speakers A common complaint against home audio systems has been the cables that interconnect the speakers to the audio receiver, tuner, cd player, or stereo units. As more and more channels are added to modern home audio equipment the problem of connecting the speakers to the audio sources has exacerbated. Running …
One of the significant developments with the widespread adoption of the personal computer for home, business, and school use is the digitalization of media and the subsequent mass adaptation by consumers and industry. While digital media is not a new concept, it has only recently made its way into the “normal” household and is commonly …
Most people usually look to Signal to Noise Ratio to measure the signal quality of either audio or video communications. Signal to noise ratio is usually written either S/N or SNR. Most of the time the signal to noise ratio is measured in decibels. A decibel is a measure of power or loudness. Not to …
The Signal to Noise Ratio is a ratio of desired signal to undesired signal (noise) in the average power level of a transmission. The signal is what you are measuring that is the result of the presence of your analyte. Noise is extraneous information that can interfere with or alter the signal. It can not …
A breakout box is a device in which a multi-cable electric line is split into its component cables in order to allow for testing or signal enhancement. There are two main types of breakout boxes. They include breakout boxes that are built to enhance or customize audio or visual signals and breakout boxes that are …
Noise-canceling headphones are headsets that have the ability not just to block out noise but to cancel it using the properties of sound waves. Sound waves have compression and rarefaction characteristics similar to the crests and troughs of a transverse wave. They also have amplitude and frequency characteristics. These characteristics of sound waves are used …
A hydrophone is a type of microphone that is specifically designed to be used under water. Hydrophones depend on piezoelectric transducers to detect sound waves and other pressure waves coming from underwater vehicles, animals, and natural structures. Hydrophones were widely used in World War I, and II to detect U-boats (German submarines) and are still …
