A digital signal processor (DSP) is a special-purpose programmable microprocessor designed to manipulate in real time a communications stream of large amounts of digital data in order to improve ...

However, the data is not necessarily encoded in the signal in the same way that equipment using or storing that data might encode it. A digital signal can be binary, but it can also be a much ...

Digital signal encoding. To optimize transmission, the signal must be encoded to facilitate its transmission on the physical medium. There are various encoding systems for this purpose that can be ...

Using the Digital Signal 0 (DS0) encoding, phone calls became digital with an 8 kHz sample rate using 8-bit pulse code modulation, working out to a maximum data rate of 64 kbps per phone line.

1. Three basic digital modulation formats are still very popular with low-data-rate short-range wireless applications: amplitude shift keying (a), on-off keying (b), and frequency shift keying (c).

The article illustrates techniques for generating parallel logic outputs with industrial serialized digital inputs.

Consequently, the narrow-band digital data (several kilohertz) is converted to a wider bandwidth signal that occupies a wide channel. In cell-phone cdma2000 systems, the channel bandwidth is 1.25 ...
