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

Transient Analysis - One of the most complex and intriguing capabilities of the
SPICE algorithm is the Transient Analysis. How do we take a collection of resistive
and energy-storage components, then find its time response to an arbitrary input
waveform? Yes, you could formulate and solve the differential equations to get the
response versus time, but SPICE is not a differential equation solver...(spice design

Versatile Power Supply Load uses Light Bulbs - 05/07/02 EDN-Design Ideas:
Improvising loads for bench-testing and designing power supplies is often a
frustrating and sometimes hazardous experience. When you push large power resistors to
their limit, they tend to burn benches and melt solder connections. Many electronic
loads are on the market.....(design idea added 1/05) |
