The TAS3204 is a highly-integrated audio system-on-chip (SOC) consisting of a fully-programmable, 48-bit digital audio processor, a 3:1 stereo analog input MUX, four ADCs, four DACs, and other analog functionality. The TAS3204 is programmable with the graphical PurePath Studio? suite of DSP code development software. PurePath Studio is a highly intuitive, drag-and-drop environment that minimizes software development effort while allowing the end user to utilize the power and flexibility of the TAS3204’s digital audio processing core.
TAS3204 processing capability includes speaker equalization and crossover, volume/bass/treble control, signal mixing/MUXing/splitting, delay compensation, dynamic range compression, and many other basic audio functions. Audio functions such as matrix decoding, stereo widening, surround sound virtualization and psychoacoustic bass boost are also available with either third-party or TI royalty-free algorithms.
The TAS3204 contains a custom-designed, fully-programmable 135-MHz, 48-bit digital audio processor. A 76-bit accumulator ensures that the high precision necessary for quality digital audio is maintained during arithmetic operations.
Four differential 102 dB DNR ADCs and four differential 105 dB DNR DACs ensure that high quality audio is maintained through the whole signal chain as well as increasing robustness against noise sources such as TDMA interference.
The TAS3204 is composed of eight functional blocks:
Clocking System
Digital Audio Interface

Power supply
Clocks, digital PLL
I2C control interface
8051 MCUcontroller
Audio DSP – digital audio processing

12bit 低功耗DAC 數模轉換器
The MAX5302 combines a low-power, voltage-output,
12-bit digital-to-analog converter (DAC) and a precision
output amplifier in an 8-pin μMAX package. It operates
from a single +5V supply, drawing less than 280μA of
supply current.

This work titled A Digital Phase Locked Loop based Signal and Symbol Recovery
System for Wireless Channel is intended to serve as a document covering funda-
mental concepts and application details related to the design of digital phase locked
loop (DPLL) and its importance in wireless communication. It documents some
of the work done during the last few years covering rudimentary design issues,
complex implementations, and fixing configuration for a range of wireless propa-
gation conditions.

Optical communication technology has been extensively developed over the
last 50 years, since the proposed idea by Kao and Hockham [1]. However, only
during the last 15 years have the concepts of communication foundation, that
is, the modulation and demodulation techniques, been applied. This is pos-
sible due to processing signals using real and imaginary components in the
baseband in the digital domain. The baseband signals can be recovered from
the optical passband region using polarization and phase diversity tech-
niques, as well as technology that was developed in the mid-1980s.

While teaching classes on digital transmission and mobile communications for
undergraduate and graduate students, I was wondering if it would be possible to
write a book capable of giving them some insight about the practical meaning of the
concepts, beyond the mathematics; the same insight that experience and repetitive
contact with the subject are capable to construct; the insight that is capable of build-
ing the bridge between the theory and how the theory manifests itself in practice.

The field of digital communication has evolved rapidly in the past few
decades, with commercial applications proliferating in wireline communi-
cation networks (e.g., digital subscriber loop, cable, fiber optics), wireless
communication (e.g., cell phones and wireless local area networks), and stor-
age media (e.g., compact discs, hard drives). The typical undergraduate and
graduate student is drawn to the field because of these applications, but is
often intimidated by the mathematical background necessary to understand
communication theory.

OSCILLATORS are key building blocks in integrated transceivers. In wired and
wireless communication terminals, the receiver front-end selects, amplifies and
converts the desired high-frequency signal to baseband. At baseband the signal can
then be converted into the digital domain for further data processing and demodula-
tion. The transmitter front-end converts an analog baseband signal to a suitable high-
frequency signal that can be transmitted over the wired or wireless channel.

The third generation (3G) mobile communication system is the next big thing
in the world of mobile telecommunications. The first generation included
analog mobile phones [e.g., Total Access Communications Systems
(TACS), Nordic Mobile Telephone (NMT), and Advanced Mobile Phone
Service (AMPS)], and the second generation (2G) included digital mobile
phones [e.g., global system for mobile communications (GSM), personal
digital cellular (PDC), and digital AMPS (D-AMPS)]. The 3G will bring
digital multimedia handsets with high data transmission rates, capable of
providing much more than basic voice calls.

Multi-carrier modulation? Orthogonal Frequency Division Multi-
plexing (OFDM) particularly? has been successfully applied to
a wide variety of digital communications applications over the past
several years. Although OFDM has been chosen as the physical layer
standard for a diversity of important systems? the theory? algorithms?
and implementation techniques remain subjects of current interest.
This is clear from the high volume of papers appearing in technical
journals and conferences.
