Circular slide rule provides quick results - 03/26/98 EDN-Design
Ideas....In analog-circuit design, most calculations you make need not be
very precise. If you need an LED-current calculation or a
coupling-capacitor value, for example,....[Design Idea by Jacek Pawlowski,

DSP Algorithm Measures Frequency & Damping - 10/08/98 EDN-Design
Ideas....The time-domain DSP algorithm described here allows you to measure the key
parameters—natural frequency and damping—in linear, second-order electromechanical
systems. The method applies to a range of electromechanical transducers
(electromagnetic or electrostatic], including dynamic speakers, seismic geophones,
micromachined sensors, and other systems....Contains several designs, scroll to find
this one. [Design Idea by Olga Belousova, Los Alamos, NM, and Alexander
Belousov, New York, NY] |

Efficient Algorithm Generates Random Signal - 12/05/96 EDN-Design Ideas....A
common way to simulate a sequence of bandwidth-limited-noise samples is to start with
a sequence of uncorrelated random numbers that have a suitable distribution and then
pass that sequence through a filter. Unfortunately, filtering affects the signal
level, and the complexity of the filter makes computations inefficient. Alternatively,
the VHDL algorithm in Listing 1 requires very little computation,....[Design Idea by
Ove Johansson, CelsiusTech Systems, Stockholm, Sweden] |

Hardware Random Number Generator - This page describes my effort to
construct a random number generator with as high a security-to-cost ratio as I can
manage. I warn anyone who intends to use any of this for anything serious to engage in
a rigorous study of the weaknesses inherent in this design. The PN junction of
Q1 is reverse biased to produce avalanche noise....[Aaron Logue] |
