Implemented ADC DAC 2 MSPS on Virtex II Pro FPGA. This is a 10 times higher in sampling rate compare to the previous post ADC DAC. The sampling rate is 2 MSPS and can go up to 4 MSPS.
So by using System Generator and a verilog blackbox I implemented an FIR high-pass filter and the result is very clean. high_pass_filter_scope_captures

A simple app. using PIC18F4520 to display frequency and period measurement of an analog square wave input. Code is written in C, interrupts and internal timer1 are utilized. Display is on 2 lined LCD screen.

Just got this microchip microcontroller sdk today. It’s the 18 series. I can’t wait to start playing with it.

I have recently join a research project group whom are working on antenna angle of arrival estimation. I believe the research project has been in its 4th year and I am currently learning on all methods or approaches to estimate the angle of arrival of the desired signals. This is something that I am interested in but it is not going to be my thesis. I am working on something related to Xilinx FPGA for my thesis.

I am starting to work on my master project/thesis now. I am feeling energetic and cannot wait to get things to work! I do have a topic in mind but may change as I progress.

I was testing on this ADC DAC chipsets at the Lab. Analog sent two each with next day delivery for free. Otherwise those can run to about 200 bucks. Kudos to Analog.

My latest resume can be downloaded in pdf format here. It was a fun HKN Electrical and Computer Engineering Honor Society dinner we had a few months ago with the professors. Below is a picture taken with my friends, Jonathan, Vinh and the professors Dr. Tim Lin, Dr Massoudi.

I have just submitted my graduate application this early morning. I went to the office of admission in the afternoon to ask a question. They told me that I should expect a letter in the mail in about 2 weeks. I am planning to start in Spring 2007. It will be a while from now.

I am planning to further my study in engineering. I am applying for a master’s degree next year and will emphasize on computer systems or communications and signal processing. I have just completed writing a statement of purpose. I have re-read it a couple of times. I think it still needs to be prove read. I would probably show it to a professor and also friends to be prove read before submission.
