12V-12V Power supply unit

04.09.98 Step-down rectifier makes a simple dc power supply

Algorithm tests for point location
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.

Audio line isolation transformer Audio line isolation circuits for preventing humming caused by ground loop

Design Ideas RISC µP implements fast FIR filter. Simple algorithm transforms filter coefficients. Door/window sensor resists tampering. Use a trick to count scope events. A primer on binary-arithmetic rounding. Light powers isolation amplifier. Low-cost feedback circuit boosts efficiency.

EDN Access -- 11.23.94 Transformer buys lower shutdown current

EDN Access -- 8.4.94 Isolation transformer passes millihertz signals

EDN Access--07.17.97 Transformer driver controls bidirectional switch

Line level to phono input Circuit to connect line level audio signals to phono input.

Method sets voltage in multiple-output converters When you design a transformer for any power converter, you face several compromises. You must trade off core size against the number of primary turns and flux density. Another trade-off is the number of turns and winding resistance versus the associated losses. After making these trade-offs, you usually arrive at a good compromise that involves the primary and secondary turns.
