New Website

CEPD is happy to announce the roll out of our newly revised website. Check it out at www.cepd.com. Let us know if you have any suggestions or comments.


Crystal Radios

CEPD gives back to the community by promoting science and engineering education. Dave presented his crystal radio workshop to the 8th grade science students at Vikan Middle School.  The students had fun building and testing their radios.

 IEEE Denver Presents Dine & Learn: 

Bumpy Flights and Passenger Frights: How Airplanes Survive Lightning

by Jennifer Kitaygorsky, PhD

The FAA (Federal Aviation Administration) requires that aircraft be protected from lightning. This means that the aircraft integrators (AI) go through a certification process for each new aircraft design, for which the electromagnetic environmental effects (E3) levels at each device fall within the design and test specifications. This talk will summarize the E3 sources, threats, and requirements that are commonly encountered, with lightning being the focus.

The Operational Amplifier
The operational amplifier is used as a basic analog building block by Electrical Engineers to accomplish functions such as amplification, filtering, adders, subtractors and various other versatile purposes. The Op-Amp can be simplified mathematically using an ideal model. Tim Groth has written a paper explaining how the ideal model simplifications lead to the equations for input impedance, output impedance and bandwidth. A link to this paper and others can be found within the presentations area on our website.

If you would like help developing a new product or if you find your project understaffed, CEPD can help you meet your deadlines. Our staff draws on years of diverse product design experience to provide creative and timely solutions for your product needs. Some of our specialties include:
  • DSP
  • Embedded Systems Hardware and Software
  • Data Acquisition
  • Wireless Sensor and Telemetry Systems (Zigbee, Cellular, VHF, Bluetooth, ANT+, etc.)
  • Control Systems
  • Programmable Logic: FPGA / PLD
  • Analog Circuit Design
  • Switching Power Supply Design
  • Battery charging (all chemistries)
  • PCB Design and Layout
  • Analysis,Test and Documentation
Our goal is to provide cost effective and expedient design options for our clients. Our services range from an hour of consultation to large turn-key product development projects. We provide detailed proposals, accurate estimates and time schedules to help you manage each phase of the project. We can offer fixed cost or time and materials proposals to suit your specific needs. There is no cost to you for the initial proposal we create and the initial discussion required!
