ISOLATED AC CURRENT MONITOR
This circuit uses a small AC current transformer from Magnetek to produce an
isolated voltage proportional to the AC current in the
primary winding. The transformer contains a single turn primary with a low
0.001-ohm resistance. It can easily handle 30 amps of AC current and provides
at least 500vac of isolation. With the components shown, the output AC voltage
is scaled so 1 amp of current produces 100mv of AC voltage.

AC Couple Analog Signals without a DC Bias Source - 02/03/00 EDN-Design
Ideas A conventional ac-coupling circuit in a single-supply system comprises
a series capacitor and a shunt resistor to ground. Unfortunately, negative
peaks of input signal can exceed 0.3V input operating-range limits of an
ADC, such as LTC1402 serial 12-bit sampling ADC. To avoid going below
ground, circuit must return shunt input.... [Design Idea by Joseph

Algorithm Tests for Point Location - 08/03/00 EDN-Design Ideas A
recent software project approximated the phase-space trajectory (also known as a
strange attractor) of a certain dynamic system by using several nonoverlapping
triangles. It became necessary to determine whether particular operating points
were on or off that attractor. Determining whether a circle or a rectangle
contains a point is trivial.... [Design Idea by Lawrence Arendt, Manitoba HVDC

Algorithm Transforms Filter Coefficients - 01/21/99 EDN-Design Ideas
To synsize infinite-impulse-response (IIR]-filter functions, expressed as H(z],
you commonly use analog prototype-filter functions, expressed as H(s], using
bilinear-z transform. This operation entails some algebraic complexity in
calculating filter coefficients. The simple algorithm shown here transforms
prototype-filter coefficients (W0, W1, W2]to IIR digital-filter coefficients
(U0, U1, U2]. These coefficients transform from.... [Design Idea by Frank Vitaljic,
