We
are excited about upgrading with this move into our new facility later
this month. We have the entire first floor. The address is
2995 Center Green Court, Suite A., Boulder, Colorado 80301, which is
just a block over from our old address. Please make a note of it.

Last
month we investigated Chua's analog chaos circuit. This month we
investigate chaos in a dsp difference equation. The logistic map
difference equation is written x[n+1] = r * x[n] * (1-x[n]). The
logistic map has been used to model population growth with r
representing the reproduction rate and x[n] the normalized population
at year n. The plot of iterative x values vs. r yields a
non-intuitive, complicated, bifurcation diagram. Notice how the
bifurcation diagram (bottom) is related to the Mandelbrot set
fractal. If you would like source code and a program which
generates a bifurcation diagram, it can be downloaded here.

If
you would like help developing a new product or if you
find your project under staffed, 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, etc.)
- Motor Control Systems
- Programmable Logic: FPGA / CPLD /
EPLD

- Analysis 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 proposals we create
and the initial discussions required!
