Useful applications are based on combining these and other functions. DSP applications affect almost every area in electronics because any application for analog electronic cir-

cuitry can be duplicated using DSP. The advantages in doing so are becoming more compelling as DSPs become faster and more cost effective.Some typical applications for

DSPs are presented in the following list:

Telecommunication

Tone Generation

Dual-Tone Multifrequency (DTMF)

Subscriber Line Interface

Full-Duplex Speakerphone

Teleconferencing

Voice Mail

Adaptive Differential Pulse Code
