The measurement of power is fundamental to transmission quality testing. Power measurements of single tones, such as the milliwatt standard, are used to adjust transmission levels.

This paper describes the design of a single-package, all-digital receiver for TOUCH-TONE® service implemented by using a digital signal processor (DSP) integrated circuit.1 The receiver is particul
A number of development tools have been designed for the singlechip digital signal processor (DSP).1 This article describes a software simulator for the DSP, dspsim, which runs under the UNIX opera
Speech synthesis is one of several promising areas of application for the digital signal processor (DSP) chip described in this issue of the Bell System Technical Journal.
Digital encoding of speech and audio has been a topic of longstanding interest for purposes of digital communications and digital storage1"3.
The application of a recently developed LSI digital signal processor, the DSP,1 to tone detection in a proposed digital CCITT NO. 5 signaling unit is described.
A tone generator is required for a number of transmission system tests.
The first, and still most heavily used, transmission medium in the telecommunications network is copper wire.
Devices for pure tone generation and detection have widespread applications. The most notable examples are Touch-Tone® signaling, frequency shift keying (FSK), a n d multifrequency (MF) signaling.
