Assistant Professor on the LCS (Communications and Signals Laboratory) of PTC (Telecom and Control Engineering Department) in Escola Politécnica (Polytechnic School from USP, University of Sao Paulo - Brazil). Research Interests:
Undergraduate Courses
PTC2547 - Introduction to Digital Television - Basic concepts on Video and Television systems engineering, covering from auditory and visual perception fundamentals, traditional analog television, cable TV, up to audio/video compression algorithms, digital coding, modulation and transmission for SDTV and HDTV.
PTC2527 - 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. PTC2528 - 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.
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.

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. Education:
