The dynamic range of an audio system is a measure of the difference between the smallest and largest amplitude values that can be represented in a medium. Digital and analog differ in both the methods of transfer and storage, as well as the behavior exhibited by the systems due to these methods.
The red digital signal is the sampled and quantized representation of the gray analog signal. A digital signal consists of a sequence of samples, which in this case are integers: 4, 5, 4, 3, 4, 6...
A symmetric layout of Charlieplexed LEDs. On left, 3 pins drive 6 LEDs arranged in a triangle. On right, 4 pins drive 12 LEDs arranged in a tetrahedron.. The Charlieplexing configuration may be viewed as a directed graph, where the drive pins are vertices and the LEDs are directed edges; there is an outward-pointing edge connected from each vertex to each other vertex, hence with n drive pins ...
Write precompensation (abbreviated WPcom in the literature) is a technical aspect of the design of hard disks, floppy disks and other digital magnetic recording devices. It is the modification of the analog write signal, shifting transitions somewhat in time, in such a way as to ensure that the signal that will later be read back will be as close as possible to the unmodified write signal.
Digital8 cassettes are identical to Video8/Hi8 cassettes and have dimensions of 95 mm × 62.5 mm × 15 mm. They are similar in size to medium-sized DV cassettes known as DVCPRO cassettes, which have dimensions 97.5 × 64.5 × 14.6 mm. Tape size is different too, 8 mm for Digital8 vs. 6.35 mm for DV.
The GS-1 (1980) was the first commercial digital synthesizer by Yamaha based on FM synthesis. For $16,000, the buyer also got a desktop computer for programming it.. In 1973, [17] the Japanese company Yamaha licensed the patent for frequency modulation synthesis (FM synthesis) from John Chowning, who had experimented with it at Stanford University since 1971.

A DDS function generator.. Direct digital synthesis (DDS) is a method employed by frequency synthesizers used for creating arbitrary waveforms from a single, fixed-frequency reference clock.
Convolution is the basic concept in signal processing that states an input signal can be combined with the system's function to find the output signal. It is the integral of the product of two waveforms after one has reversed and shifted; the symbol for convolution is *.
