Algorithm Transforms Filter Coefficients – 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  s (analog)domain to  z (digital)domain….

AC Couple Analog Signals without a DC Bias Source – 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….
