Hi, I am looking for someone to design a Downconverter/ Upconverter for Xlinx FPGAS. The design parameters are the following: Data rate: 200 kbps Modulation type: QPSK FPGA system sampling rate: 150 Mhz IF carrier frequency: 12.8 Mhz Oscillator type: Cordic Adjacent channel rejection: -40dBs I can pay up to 700 euros but the amount is discussable. Many parts of the system (e.g filters, QPSK) and an instruction book are available here:   [obscured]  /u/9537436/EE580_980_DSP_Primer_Notes.zip. Any implementation can be used as long as it works. The total amount spent in the project for an experienced designer should be no more than 30 hours. The delivered product should include the final model (Simulink and MATLAB files) and a technical report. Your design files must be organised in such a way that they can be easily opened and run, e.g. you should clarify the necessary directory structure and include a "readme" file as appropriate. The technical report is expected to ...

Summary: I need a pcb design for a small, light-weight, microprocessor-controlled, and easy to assemble transmitter to attach to small animals. Requirements ? Transmission should be in the band between 150.8 and 151.8 MHz. Each unit should have a different band separated by at least 10kHz (i.e. one transmitter might have a band of 150.890 and another 150.880). ? Weight less than 15 grams (ideally). The entire unit should be less than 1cm by 1cm. ? Range should be approximately 1Km ? Battery life should be a minimum of 3 months ? Pulse rate of approximately 1 pulse/second ? On-off controlled by tiny reed switch (magnetic) The units should be designed so that they can be easily constructed (using a tiny pcb as a base). There should be a set of 2 wire leads that would lead out to a small battery. A second lead should be for a wire whip-style antenna. I realize that there are commercial versions of this product available. I am looking for something that students can build on their own...

Hi I'm doing exactly the same project (  [obscured]  /underground-cable-fault-distance-locator ) The only problem is that I need to replace the 8051microcontroller and ADC with the best microcontroller that it has ADC in it and it will do the same job?! The microcontroller I'm using is AT89S52 and outside ADC 8 bits ,single channel IC and take one analogy signal as input I need to replace them with a microcontroller that has built-in ADC, from ATMEL that is the same as AT89S52 but has ADC built-in

We would like to design and manufacture a diesel monitor for marine diesel engines. The unit should monitor the amount of fuel been used. With a display the unit would show litres per hour used and total consumption. We also like to include the possabilty to be able to email results to an address. Also if we could incorporate live monitoring also?. The unit needs to be cost effective for small boats to buy. There is already plenty of expensive models on the market.

Computer engineering is a discipline that integrates several fields of electrical engineering and computer science required to develop computer hardware and software.[1] Computer engineers usually have training in electronic engineering (or electrical engineering), software design, and hardware-software integration instead of only software engineering or electronic engineering. Computer engineers are involved in many hardware and software aspects of computing, from the design of individual microprocessors, personal computers, and supercomputers, to circuit design. This field of engineering not only focuses on how computer systems themselves work, but also how they integrate into the larger picture.[2] Usual tasks involving computer engineers include writing software and firmware for embedded microcontrollers, designing VLSI chips, designing analog sensors, designing mixed signal circuit boards, and designing operating systems. Computer engineers are also suited for robotics research, ...
