- Telecom Graduation Project - Phase I - This is a semester course on which
students define the scope of their graduation projects, as well as
schedules and other requirements. Some lectures on design techniques,
CAD tools, programmable logic and printed circuits design are also given
in this course.

- Telecom Graduation Project - Phase II - In this course the
students will implement their graduation projects, following guidelines
developed in the precedent semester (in PTC2527). Projects generally
consist of some communications system, sub-sytem or related
electronic circuit; can also be a computer program related to
Telecommunications.

Some
Projects:
100 kHz Spectrum Analyzer - This is a dual-channel spectrum
analyzer, with built-in test signal generator (noise and sinewave). It
uses two DSP in a master-slave configuration; processed data is sent to
a PC by Ethernet interface. Click here
to see an image of its PCB.
BrainNet BNT-36 - This
32-channel EEG equipment uses a DSP for filtering, and has capability to
meqasure electrode impedance in real time, without interfering with the
exam. Click here to see an image of one of its PCB.
Video
Projects
- See a "Videowall" (digital video equipment developed originally for Philips, to
be used in its stand in an electronics fair in 1987), a B-MAC decoder
protype, and other Video related projects. Click here
to see
an image of a recent Videowall PCB, designed to accept SVGA input. 8-Channel Data Acquisition Interface -
This is a fully programmable transducer conditioning, amplifier and
digitizer board used in a data acquisition system. Click here
to see an
image of its PCB. Analog Processing Board for Optical
Gyro - This board contains laser power supply, temperature
control, photodetector amplifier and analog signal processing for an
optical fiber gyroscope. Click here to
see an image of its PCB.
Programmable
Sound Synthesizer - This musical instrument, developed and built around 1975,
operated under computer control (initially by "Ugly Duck", the
first brazilian computer, and later by an Hewlett-Packard HP-21MX
minicomputer). Audio waveforms were digitally generated.
